Italian Alchermes Layered Custard Dessert | Zuppa Inglese all'Alchermes
Updated: 5 days ago
Zuppa inglese is the dessert Emilia Romagna built out of three things it already had: sponge cake, pastry cream and a bottle of Alchermes. There is no cream whipped into it, no gelatine, no mascarpone and no coffee. Layers of pan di Spagna brushed with the crimson spiced liqueur alternate with vanilla custard and chocolate custard, the whole thing is chilled overnight, and it is served cold in a glass dish or cut into squares so that the red, the pale yellow and the brown read as three distinct bands.
It is not a soup and it is not English, and both halves of the name have explanations that are better than the dessert's reputation suggests. What makes it work is the contrast between a sponge carrying alcohol, cinnamon, clove and rose, and two custards built from one single base so that they set to exactly the same softness. Get that base right and the dessert is almost impossible to ruin. Get it wrong and it slides apart on the spoon.
This version uses the classic Romagnolo proportions, one custard divided in two while it is still hot, a diluted Alchermes brushed rather than poured, and a full overnight rest. The method below is written for a shallow rectangular dish, which portions far better than a deep bowl, but the same quantities work spooned straight out of a glass trifle bowl.
Yield: 8 servings. Prep: 1 hour. Cook: 20 minutes. Chill: at least 6 hours, overnight preferred. Total: about 7 hours 30 minutes. Difficulty: advanced. Course: dessert. Region: Emilia Romagna, with versions across Tuscany, Umbria, the Marche and Lazio.
The Story
The name is the first puzzle and the easier one. Zuppa here has nothing to do with soup: it comes from inzuppare, to soak or to dunk, the same root that gives the English word sop, and it was used in old Italian for any dish of bread or cake steeped in liquid. Inglese is harder. The most repeated account places the dessert at the court of the Este dukes in Ferrara in the 16th century, where cooks are said to have reconstructed from description the trifle that Italian diplomats had eaten at the English court, using the sponge and custard they had to hand. A rival Romagnolo account holds that the dessert already existed locally as zuppa del duca, the duke's soup, and only acquired its English label later, when English residents in Tuscany took to ordering it.
Whichever came first, the dessert settled in Emilia Romagna and never really left. Forlì, Ravenna, Ferrara and Bologna each claim a version, and the differences are small but defended: some use only Alchermes, some add a second liqueur such as rosolio or rum, some insist on chocolate custard and some use only vanilla. The one fixed point is the soaked sponge. In Romagna it is made in ordinary households for Sunday lunch, not for feast days, and it is the dessert most often cited when Bolognese and Romagnolo cooks argue about who owns what.
Alchermes carries its own history, and it is Florentine rather than Emilian. It was compounded from the Renaissance onwards by the Dominican friars of the Officina Profumo Farmaceutica di Santa Maria Novella in Florence, who sold it as a cordial and a tonic, and it became associated with the Medici to the point of being called the liqueur of the Medici. Its name comes through Spanish and Arabic from al qirmiz, the kermes insect whose dried bodies gave the brilliant scarlet dye that coloured it, and which also gives us the word crimson. The modern liqueur is coloured with cochineal and scented with cinnamon, clove, nutmeg, mace, coriander and rose water, which is why a sponge brushed with it tastes of far more than sugar and alcohol. Without Alchermes this dessert is simply cake and custard; with it, it is zuppa inglese.
Ingredients
For the pastry cream base
Whole milk, 3 cups (710 ml)
Egg yolks, large, 6
Granulated sugar, 3/4 cup (150 g)
Cornstarch, 1/3 cup (40 g)
Vanilla extract, 1 tsp (5 ml), or 1 split vanilla pod
Lemon zest, 2 wide strips, no white pith, traditional and optional
Fine sea salt, 1 small pinch
For the chocolate custard
Pastry cream, exactly half of the batch above, about 1 lb 2 oz (510 g)
Dark chocolate, 60 to 70 percent cacao, finely chopped, 3 oz (85 g)
Unsweetened cocoa powder, 1 tbsp (5 g), optional, for a darker colour
For soaking and assembly
Pan di Spagna sponge cake, or savoiardi, 10 oz (285 g)
Alchermes, 1/2 cup (120 ml)
Water, 1/4 cup (60 ml)
Granulated sugar, 2 tbsp (25 g), optional, only if the liqueur is dry
For finishing
Dark chocolate for grating, 1/2 oz (15 g)
Alchermes, 1 tbsp (15 ml), reserved undiluted for the top sponge layer
Preparation
Step 1
Infuse the milk. Put the milk, the vanilla and the lemon zest strips into a heavy saucepan and bring it slowly to the point where steam rises and the surface trembles, without letting it boil. Take it off the heat and leave it to infuse for 10 minutes, then lift out the zest. Ten minutes is enough for the oils in the peel to move into the milk and not long enough for any bitterness to follow them. If you are using a vanilla pod, split it, scrape the seeds into the milk and leave the pod in for the whole infusion.
Step 2
Whisk the yolks, sugar and starch. Whisk the egg yolks with the sugar until the mixture pales and thickens, about a minute by hand, then whisk in the cornstarch and the pinch of salt until there is not a single lump left. Do this while the milk infuses rather than beforehand: yolks left sitting on dry sugar develop hard granules that never dissolve and show up later as specks in a finished custard. The mixture should fall from the whisk in a smooth ribbon.
Step 3
Temper and cook the cream. Pour about a third of the hot milk into the yolks in a thin stream while whisking hard, then return everything to the saucepan. Cook over medium heat, whisking constantly and reaching into the corners of the pan, until the cream thickens suddenly and then releases its first slow bubbles. Hold it there for a full minute, still whisking. That minute is not optional: cornstarch only reaches its full setting power once it has boiled, and a cream pulled off before it will taste raw and slacken overnight in the refrigerator.
Step 4
Divide the batch by weight. Take the pan off the heat and divide the hot cream into two containers on a scale, not by eye. Each half should weigh about 1 lb 2 oz (510 g). Accuracy here is what makes the two layers set to the same firmness and the finished slice look even, and it takes ten seconds. Put one half aside as the vanilla custard.
Step 5
Make the chocolate custard. Add the finely chopped chocolate, and the cocoa powder if you are using it, to the second half while it is still hot, wait 30 seconds for the heat to do the work, then whisk from the centre outwards until the custard is glossy and uniform. Chopped chocolate melts almost instantly at this temperature; a bar broken into chunks will not, and you will be left with unmelted flecks. Do not put the pan back on the heat to help it along, because the emulsion will tighten and go grainy.
Step 6
Cool both custards fast. Spread each custard no more than an inch deep in a shallow dish, press a sheet of plastic film directly onto the surface so no air touches it, and refrigerate until completely cold, at least 3 hours. Shallow and covered matters twice over: it takes the custard through the warm temperature range quickly, and it stops the skin that otherwise forms and later breaks up into lumps during assembly.
Step 7
Mix the soaking liqueur. Stir the Alchermes with the water, and with the sugar only if your bottle tastes dry. Commercial Alchermes varies considerably in strength and sweetness between producers, so taste the mixture: it should be sweet, clearly perfumed with cinnamon and clove, and drinkable rather than fiery. Keep 1 tablespoon of undiluted liqueur back for the final sponge layer, where a stronger colour reads well through the glass.
Step 8
Cut the sponge. Slice the pan di Spagna into even sheets about 1/2 inch (12 mm) thick and cut them to fit your dish, trimming rather than tearing so each layer sits flat. Uneven sponge is the single most common reason a zuppa inglese leans. If you are using savoiardi, lay them in tight rows with no gaps and remember that they take up liquid two or three times faster than sponge cake.
Step 9
Soak and build the first layers. Whisk both cold custards briefly to loosen them to the same smooth consistency. Brush the first sheet of sponge on one side only with the diluted Alchermes, using a pastry brush and stopping while the cake is clearly red but still firm when pressed. Lay it soaked side up in the dish, spread half of the vanilla custard over it to the edges, and level the surface with an offset spatula. Never pour the liqueur from the bottle: it lands unevenly and the sponge collapses wherever it pools.
Step 10
Complete the layers. Add a second brushed sponge sheet, spread half the chocolate custard, then a third sponge sheet, the remaining vanilla custard, a fourth sponge sheet brushed with the reserved undiluted Alchermes, and finally the rest of the chocolate custard. Press each sponge layer down gently with your palm to expel trapped air, and make sure every custard layer reaches the walls of the dish so there are no hollows for the layers to slide into.
Step 11
Chill overnight. Cover the dish and refrigerate for at least 6 hours and preferably a full night. The dessert changes measurably during that rest: the starch finishes setting, the sponge hydrates evenly instead of in patches, and the raw alcohol edge of the Alchermes softens into spice and rose. Zuppa inglese served after two hours tastes of liqueur; served the next day it tastes of the dessert.
Step 12
Finish and serve. Take the dish out 10 minutes before serving, grate a little dark chocolate over the top and cut portions with a thin blade wiped clean between every cut, or serve it spooned from the dish. Do not add whipped cream. The three bands of colour are the entire visual argument of the dessert and anything piled on top hides them.
Plating
Zuppa inglese is a dessert you see before you taste, so whatever vessel you choose has to show the section. A straight sided glass dish is traditional and still the best choice, because the crimson sponge, the pale vanilla and the dark chocolate stack up as three readable bands from the side. If you assemble in a ceramic dish instead, portion it and plate the squares rather than serving from the dish, or the whole point of the layering is lost.
For cut portions, use a thin bladed knife warmed under hot water and dried, cut straight down in one movement without sawing, and wipe the blade after every single cut. Alchermes stains, and one careless pass drags a pink smear across the vanilla custard that no amount of tidying will remove. Lift each square with a small offset spatula onto a chilled plate, slightly off centre, and leave the plate otherwise empty.
Grated dark chocolate over the top is the only garnish that belongs, and a light hand is the point: enough to break the flat surface of the last custard layer, not enough to mask its colour. A few small amaretti or a shard of pan di Spagna toasted until crisp can be leaned against a portion for texture, but skip cocoa powder, which dulls everything, and skip mint, which has never been anywhere near this dessert.
Professional Technique
The whole dessert stands on one decision: a single pastry cream divided in two while hot, rather than two custards cooked separately. Cooked separately, two batches will differ in how far the starch gelatinised, how much water evaporated and how firmly they set, and layers of different firmness shear against each other when a spoon goes in. Divided by weight from one pan, the vanilla and chocolate halves are structurally identical and differ only in flavour. The chocolate half sets marginally firmer because cocoa butter solidifies at refrigerator temperature, which is exactly why the chocolate layers work better at the bottom and the top of the stack.
The cornstarch is the second piece of engineering, and it behaves quite differently from the flour used in some older Romagnolo versions. Starch granules only swell and burst above about 205°F (96°C), which is why the custard has to reach and hold a genuine bubble for a full minute; stopped short, the granules stay intact, the cream looks thick from the heat alone and then slackens as it cools. Cornstarch also keeps thickening for hours in the refrigerator, so the correct cream looks slightly too loose in the pan. Adding more starch to compensate for an undercooked custard produces the rubbery, sliceable texture that marks out a bad zuppa inglese.
The third technique is controlling how much liquid the sponge takes. A brush applies the diluted Alchermes at roughly a tablespoon per layer and lets you see saturation build; dipping or pouring delivers three or four times that and saturates the crumb past the point where it can hold custard above it. Diluting the liqueur with a third of its volume in water is not an economy, it is a control: it lowers the alcohol enough that the cake absorbs slowly rather than instantly, and it keeps the colour even. A properly brushed layer is clearly red, springs back when pressed, and releases nothing onto the plate.
Texture and Moisture Control
Three moisture levels have to coexist in the finished dish and none of them should migrate into the others: sponge that is damp and aromatic, custard that is soft enough to spoon but holds a clean edge, and a surface that stays matte rather than weeping. The overnight rest is what equalises them. During those hours moisture moves out of the wettest parts of the sponge into the drier crumb next to it, so patches even out, while the starch network in the custard finishes tightening and traps the water it is holding.
Temperature discipline runs through the whole method. Both custards must be genuinely cold, below 40°F (4°C), before anything is layered. Custard that is merely cool goes on more thinly, slides on the sponge and keeps cooking the cake underneath it, and a dessert assembled warm will still be sitting at an angle the next morning. At the other end, do not serve it near freezing: below about 37°F (3°C) the cocoa butter in the chocolate layer sets hard and the custard reads waxy instead of creamy. The window is a normal refrigerator, taken out ten minutes ahead.
If your custard has set very firmly, whisk it for ten seconds before spreading rather than warming it. Starch set is thixotropic, which means agitation alone loosens it back to a spreadable consistency and it recovers its body once it is left alone again. Heat, on the other hand, breaks the set permanently and the layer will never firm up again. The same rule applies to a cream that has been in the refrigerator overnight before assembly: whisk, never warm.
Professional Mise en Place
Zuppa inglese is almost entirely a make ahead dessert, which is why it appears on trattoria menus across Romagna. Nothing is finished to order, the custards can be cooked the day before assembly, and the assembled dish actively improves with a night in the refrigerator. Scale it by weight and it becomes completely repeatable.
Equipment and tools
Digital scale, needed for dividing the custard base accurately
Heavy saucepan, at least 3 quart, and a balloon whisk
Two shallow dishes for cooling the custards, plus plastic film
Pastry brush, offset spatula and a serrated knife for the sponge
Straight sided glass dish, about 8 by 8 inches (20 by 20 cm), chilled
Prepared ahead
Pan di Spagna baked, up to 2 days ahead, in fact easier to slice on day two
Both custards cooked, divided and chilled, up to 24 hours ahead, covered on the surface
Alchermes diluted and measured into a jug, up to 1 week ahead
Sponge sliced and cut to the dish, on the day, kept covered so it does not dry
Dessert fully assembled, 12 to 24 hours ahead, covered and refrigerated
Service setup
Dessert out of the refrigerator 10 minutes before the first portion, no longer
Thin blade in hot water with a clean cloth beside it, wiped between every cut
Plates chilled, chocolate grated only at the moment of service
Offset spatula for lifting squares, never a fish slice or a spoon
Any second dish kept covered and cold until the first is finished
Chef Tips
Buy real Alchermes and check the label. A number of cheap bottles are simply sweetened alcohol with colouring and no spice at all, and they give you the crimson without the cinnamon, clove and rose that are the entire reason the liqueur is in this dessert. The versions still made to old Florentine formulas smell of spice cabinet before you taste them. If you genuinely cannot find any, a mixture of rosolio with a little cinnamon and clove infusion is closer in spirit than a synthetic red liqueur.
Use day old sponge. A pan di Spagna baked the same morning is fragile, tears under the brush and takes up liquid greedily and unevenly. Left uncovered overnight it firms enough to slice cleanly and absorbs at a rate you can actually watch and stop. This is the opposite of the advice you would give for eating cake plainly, and it is the single easiest improvement to make to this recipe.
Assemble it in the dish you will serve from and do not attempt to unmould it. Zuppa inglese is not a charlotte and it has no gelatine holding it together; it is held up entirely by set custard and hydrated sponge, and turning it out simply collapses it. If you want the drama of a tall dessert, build it in individual glasses instead, with three thin layers each.
Make it a full day ahead whenever you can. Almost every dessert loses something overnight and this one gains: the alcohol softens into aroma, the sponge finishes hydrating, the two custards reach their final set, and the colours bleed just enough at the boundaries to look right. A zuppa inglese eaten the same evening it was built is a decent dessert. The next day it is the real thing.
Common Mistakes
Layering with custard that is not fully cold. Warm cream spreads too thin, keeps cooking the sponge beneath it and lets the whole stack slump sideways overnight. Chill both custards below 40°F (4°C) in shallow dishes before you even cut the sponge.
Pouring the Alchermes instead of brushing it. Poured liqueur soaks through in patches and floods wherever it pools, and the cake there loses all structure. Brush one side only, about a tablespoon per layer, and stop when the sponge is red but still springs back.
Pulling the pastry cream off before it bubbles. Cornstarch has to boil to reach its full setting power, so a custard removed at the first sign of thickening will taste faintly raw and slacken in the refrigerator. Hold it at a slow bubble for a full minute, whisking.
Adding extra starch to fix a loose custard. The problem is almost always undercooking, not the recipe, and more cornstarch gives a bouncy, sliceable cream that feels like set pudding rather than pastry cream. Cook it properly instead.
Melting the chocolate into cream that has already cooled. Below about 120°F (50°C) the chopped chocolate will not disperse and you get flecks suspended in pale custard. Add it to the hot half straight off the heat and whisk from the centre outwards.
Using savoiardi as though they were sponge cake. Dry biscuits take up liquid several times faster and go to mush in seconds under the same brushing. Use noticeably less liqueur, brush both sides very lightly and work quickly.
Serving it the same day. Two hours in the refrigerator gives you a dessert that tastes mostly of alcohol, with dry patches in the sponge and custard that has not finished setting. Six hours is the minimum and a full night is what the recipe is written for.
Wine Pairing
The dessert already brings its own alcohol and a heavy load of warm spice, so the wine has to be sweeter than the plate, gentle in strength and aromatic enough to stand next to cinnamon and clove without arguing with them. It also has to cross two very different layers, a vanilla custard and a dark chocolate one.
Romagna Albana DOCG: The local answer, and in its passito form the most natural one on this list. Albana has unusually thick skins for a white grape, which gives the dried grape version a light tannic grip alongside apricot and candied peel, and that grip stops it being swallowed by the custard. It comes from the same hills as the dessert, and the pairing has the logic of proximity behind it as well as taste.
Vin Santo del Chianti Classico DOC: A Tuscan choice that echoes the Florentine origin of the Alchermes itself. Years in sealed caratelli under a warm roof give it a deliberately oxidative character of walnut, dried fig and orange peel, and those notes sit against the spice of the liqueur rather than duplicating it. Its acidity is high enough to keep a rich custard dessert from cloying.
Recioto di Soave DOCG: Garganega dried on racks through the winter, pressed sweet and left lightly honeyed rather than syrupy. It is the most delicate wine here and the best partner for the vanilla custard specifically: white flowers, almond and ripe pear meeting cream and egg yolk without any spice of its own to compete. Serve it at 50°F (10°C) in a small glass.
Brachetto d'Acqui DOCG: Lightly sparkling, low in alcohol and openly perfumed with rose and strawberry, which is precisely the register the Alchermes is working in. The bubble scrubs custard fat off the palate and the rose note picks up the rose water in the liqueur almost note for note. It is also the one wine here that handles the chocolate layer comfortably.
Moscato di Scanzo DOCG: A rarity from a few hectares above Bergamo, made from red Moscato grapes dried on trays and aged for years. It smells of rose, sage and dried cherry and carries a fine tannin that meets dark chocolate head on, where most sweet whites simply slide past it. Expensive and worth pouring in very small measures alongside the last spoonfuls.
Storage & Reheating
This is a cold dessert and there is nothing to reheat. Keep it covered in the refrigerator, in the dish it was assembled in, for up to 3 days. It is at its best between 12 and 24 hours after assembly; by the third day the sponge has given up most of its structure and the boundaries between the layers have blurred, which affects appearance more than flavour. Cover it with film pressed lightly over the dish rather than sealed tight, and keep it away from anything strongly aromatic, since custard picks up refrigerator smells quickly.
The components keep better separately than the assembled dessert. Both custards hold for 2 days in the refrigerator in airtight containers with film on the surface, and both should be whisked smooth before use. Diluted Alchermes keeps for weeks in a sealed bottle at room temperature. Pan di Spagna keeps for 2 days wrapped at room temperature and improves for slicing, or for 1 month wrapped and frozen.
Do not freeze the finished dessert. Starch bound pastry cream separates on thawing and releases water, and soaked sponge turns to paste, so what comes out of the freezer is a grey and weeping version of what went in. If you need to work far ahead, freeze the sponge alone, keep the custards to their 2 day window and assemble the day before service.
