Torta di Mele della Nonna (Italian Grandmother's Apple Cake)

A grandmother's apple cake is mostly apple. Just enough batter holds the wedges together, so each slice looks slightly precarious and tastes of fruit rather than sponge. Two pounds of apple meet seven ounces of flour, and that ratio is the whole recipe. It is made in one bowl, with a hand whisk and melted butter, and it is better on the second day than on the first.

Yield: 8 servings from one 9 inch cake. Prep: 30 minutes. Bake: 55 to 65 minutes. Difficulty: easy.

The Story

Apples are not a Mediterranean fruit the way olives and citrus are, and Italian apple growing sits in places that look nothing like the postcard. The Val di Non in Trentino and the Val Venosta in Alto Adige carry most of the national crop, in orchards where bright days and cold nights build acidity and keep the flesh firm. Renetta Canada, the matte, greenish, irregular apple, was the baking apple of those valleys for generations. In Campania the equivalent was the small Annurca, ripened on beds of straw and prized for a sharp, mineral bite.

The cake itself belongs to a much more recent Italy. Domestic ovens became normal in Italian kitchens only through the 1950s and 1960s. Before that, a family that wanted something baked carried its dough to the village baker, which is why so much older Italian sweet cooking is fried, boiled or cooked on a griddle. The torta di mele arrived with the home oven and with the merenda, the mid afternoon snack that children ate after school and adults took with coffee. It asked for one tin, one bowl and whatever fruit the tree had produced that week, and it never needed a recipe card written down, because every cook learned it standing beside someone older.

The phrase della nonna is a register rather than a recipe. It promises a domestic cake made without special equipment, without a fancy finish, and with more fruit than seems sensible. No two Italian households make the same one, and none would recognise a definitive version. Friuli splashes grappa over the apples. Trentino adds a little cinnamon and sometimes raisins soaked in the same spirit. The Campanian version made with Annurca takes no spice at all, because the fruit is too pronounced to want any.

The clearest divide is fat. North of the Apennines the batter is made with butter, which gives a tender crumb and a rich edge. Further south olive oil takes over, and the cake turns lighter and slightly fruity, a habit that follows the olive groves as faithfully as the butter follows the dairies of the Alpine valleys. This version follows the northern line, with melted butter whisked into eggs and milk, and the sweetness kept low so the acidity of the apple stays audible. It is a cake for the Sunday table, the school bag and the corner of a bakery counter, and it has survived because it is honest, generous and almost impossible to improve by complicating it.

Ingredients

For the apples

Renetta Canada apples, or another firm tart baking apple such as Bramley or Granny Smith, 2 1/4 lb (1 kg) before peeling, about 5 medium
Lemon, 1, finely grated zest and 2 tbsp (30 ml) juice
Ground cinnamon, 1/2 tsp (1 g), optional, in the Trentino style
Grappa or dark rum, 1 tbsp (15 ml), optional, in the Friuli style

For the batter

All purpose flour, 1 2/3 cups (210 g)
Granulated sugar, 3/4 cup (150 g)
Large eggs, 3, at room temperature
Whole milk, 1/2 cup (120 ml)
Unsalted butter, melted and cooled, 5 tbsp (70 g)
Baking powder, 2 tsp (8 g)
Fine sea salt, 1/4 tsp (1.5 g)
Vanilla extract, 1 tsp (5 ml)

For the pan

Unsalted butter, softened, 1 tbsp (14 g)
All purpose flour, 1 tbsp (8 g)

For finishing

Granulated sugar, for the top layer only, 1 1/2 tbsp (19 g)

For serving

Heavy cream, lightly whipped and unsweetened, 1/2 cup (120 ml), optional
Freshly brewed espresso or coffee, to pour alongside, 4 small cups

Preparation

Choose and cut the apples

Peel, quarter and core the apples, then cut each quarter into wedges about 1/3 inch (8 mm) thick at the outer edge. Keep the wedges thick, because fruit you can see and bite is the point of the cake. Set aside the neatest fifth of the wedges on a plate for the top layer, and keep them plain and dry.

Toss the apples in lemon

Put the remaining wedges in a bowl with the lemon zest and juice, plus the cinnamon and the grappa if you are using them, and turn them with your hands. Leave them for 15 minutes. The acid keeps the cut surfaces from browning. No sugar goes in at this stage, because sugar would draw the juice out into the batter. Drain the wedges before using them.

Prepare the pan and the oven

Heat the oven to 340°F (170°C), conventional rather than fan, with a rack in the lower third. Butter a 9 inch (23 cm) springform tin thoroughly, right into the angle where base meets side, then dust it with flour and knock out the excess. Line the base with a disc of parchment.

Whisk the eggs and sugar by hand

Break the eggs into a large bowl, add the 3/4 cup of sugar and the salt, and whisk by hand for 2 to 3 minutes. You are only dissolving the sugar and loosening the eggs, so the mixture should turn smooth and a shade paler without holding a ribbon. Whisk in the vanilla.

Add the milk and the melted butter

Whisk in the milk, then pour in the melted butter in a steady stream while you keep whisking. The butter should be barely warm, around 95°F (35°C), because hot butter cooks the egg at the edge of the bowl and leaves small set specks. The mixture looks thin and slightly separated now, and it recovers when the flour goes in.

Fold in the flour in two additions

Sift the flour and baking powder over the bowl in two goes, folding with a spatula until each addition has just disappeared. Stop as soon as no dry flour shows. The batter should be thick, close to a heavy pancake batter, because a thin batter cannot hold this much fruit.

Fold in the apples and fill the tin

Tip the drained apples into the batter and fold from the bottom until every wedge is coated. It looks like far too much fruit, and it is meant to. Scrape everything into the tin and level it gently with the back of a spoon, without pressing down.

Arrange the top layer and sugar the surface

Lay the reserved wedges over the surface in overlapping circles, resting each one on the batter and pressing it in only far enough to hold. Just before the tin goes into the oven, scatter the 1 1/2 tablespoons of sugar evenly over the top. Sugar sprinkled any earlier has time to draw juice and pool.

Bake uncovered

Bake on the lower rack for 55 to 65 minutes, and never cover the tin. The cake is done when the top is deep gold and glossy, the edges pull slightly from the tin, and a skewer pushed between two wedges into the batter comes out with a few moist crumbs but no raw batter. If the top colours too fast, lower the oven by 10°F (5°C) for the last 15 minutes.

Cool and unmould

Leave the cake in the tin on a rack for 20 minutes, then release the ring and leave it on the base for at least 40 minutes more. It should be barely warm before you cut it, because the crumb finishes setting as it cools and a hot slice collapses.

Plating

Serve the cake in wedges from the tin base or a plain plate. Cut with a long thin knife wiped between cuts, because the blade drags cooked apple otherwise and the cut face turns ragged. Eight generous wedges from a 9 inch cake is right, and twelve small ones leave each slice too shallow.

Serve it barely warm or at room temperature, never hot. Leave the glossy top exactly as it came from the oven, with no dusting of confectioners sugar, which would dull the shine. A spoonful of lightly whipped unsweetened cream can sit beside the wedge rather than on it. In Italian homes it goes out in the middle of the afternoon with coffee, and at that hour it is served plain.

Professional Technique

The shine on this cake comes from one small piece of physics, not from jam or gelatin. Sugar scattered over the cut faces of the apple slices sits at a far higher concentration than the fluid inside the apple cells. Water moves across the cell membranes toward the more concentrated side, which is osmosis, so the sugar pulls water out of the fruit. Within minutes each slice carries a thin film of syrup, made of sugar dissolved in the apple's own juice, and the effect starts long before the oven does.

In the oven that film keeps working. The heat drives off the water, the syrup reduces and thickens, and the sugars set with the apple pectin on the surface into a thin, clear, glossy glaze. The apple builds its own lacquer, which is why the top brightens without any brushed on coating and why no two cakes shine in quite the same way, since every apple gives a slightly different juice.

Every rule of the method follows from this. The sugar goes on only at the end, and in a small amount, because too much makes more syrup than the oven can reduce and the top stays wet and weeps, while sugar added earlier draws the juice down into the batter. The slices are rested on the batter and not sunk into it, so the cut faces stay exposed to the sugar and the dry oven air, and the batter cannot rise over them. And the cake is never covered while it bakes, because trapped steam condenses on the surface and dissolves the glaze back into syrup.

Texture and Moisture Control

Texture here is a negotiation between the fruit and the batter. Renetta Canada carries high acid and a high proportion of dry matter to water, so it keeps its shape and its flavour through an hour of heat. Annurca, Bramley, Granny Smith and Belle de Boskoop behave the same way. Gala, Fuji and Pink Lady are bred for a crispness that comes from water pressure inside cold raw cells, and it collapses in the oven, leaving a sweet, vague, slightly soapy cake.

Because more than half the weight is apple, the cake bakes like a gratin. At 350°F (175°C) or higher the crust sets and colours long before the centre is done, and you overbake the outside rescuing the middle. At 340°F (170°C) on a low rack the whole mass reaches doneness together. Skip the fan: moving air dries the exposed apple before the interior catches up.

Melted butter, not creamed, keeps the crumb dense and moist, and the short whisk keeps gluten low. Cooling matters as much as baking, because the starch and the fruit juices only set as the cake cools. Slice it hot and the crumb smears. Wait an hour and it cuts clean, with the apple wedges holding their outline in the cut face. The baking powder gives lift, but the eggs do the structural work, which is why they must be at room temperature and whisked only briefly.

Professional Mise en Place

Equipment and tools

You need a 9 inch (23 cm) springform tin, a large bowl, a hand whisk, a spatula, a sieve, a long thin knife and an oven thermometer, plus a wire rack for cooling. The thermometer earns its place, because many home ovens run 25°F (15°C) hotter than the dial says.

Prepared ahead

Cut the apples up to 2 hours ahead and hold them in the lemon. Melt and cool the butter, weigh the flour with the baking powder, and prepare the tin. Do not mix the batter ahead, because the baking powder starts working the moment it is wet. Keep the reserved top wedges on a separate plate, uncovered, so their cut faces stay dry until the sugar goes on.

Service setup

Rest the cake on a rack, then move it to a board. Keep a jug of hot water beside the knife for wiping the blade between cuts. Whip any cream to soft peaks only at the last minute, and have the coffee ready. Warm plates are unnecessary, since this cake is best served barely warm or at room temperature.

Chef Tips

Weigh the apples after peeling and coring, not before. Two pounds of raw apple with the peel and core still on gives a noticeably thinner cake, because a fifth of that weight goes in the bin.
Choose apples of different sizes if you like, but cut them to one thickness, so every wedge softens at the same rate and none stays firm in the middle.
Rest the top wedges on the batter with their cut faces up and lightly overlapping, so the sugar lands on exposed flesh rather than on skin, and the finished surface looks like a pattern of petals.
Bake the cake a day ahead when you can. The juices redistribute overnight, the flavour deepens, and the crumb slices far more cleanly the next afternoon.

Common Mistakes

Sugaring the apples early. Sugar mixed into the wedges draws their juice into the batter and turns the crumb gummy. Keep it for the top layer, just before baking, and use only the small amount the recipe gives.

Sinking the top slices. Pressed deep, they vanish under the rising batter and the surface bakes pale and matte. Rest them on top and press only enough to hold.

Covering the tin with foil. Steam condenses on the surface and washes the glaze away. Bake uncovered and lower the heat instead if the top darkens.

Baking at 350°F (175°C) or hotter. The top browns and the edges dry while the middle is still raw. Stay at 340°F (170°C), on a low rack, and give the cake the full hour.

Using a soft eating apple. Gala and Fuji collapse into sweet mush. Choose a firm tart baking apple such as Renetta Canada, Annurca or Bramley, even if it looks plain.

Overmixing the batter. Beating after the flour goes in builds gluten and gives a tough, rubbery cake. Fold until the flour just disappears.

Wine Pairing

Ramandolo DOCG: Verduzzo Friulano dried on the vine gives quince, honey and dried apricot, very close to a Renetta after an hour in the oven. Its thick skins add a faint tannic grip that clears the butter from the palate between forkfuls, so the wine and the cake keep refreshing each other. Serve it lightly chilled.

Romagna Albana DOCG: Choose the passito. Albana has thick skins, and drying concentrates them into dried fig and candied peel over a bitter almond finish. That bitterness stops the pairing from being sugar against sugar, and the acidity meets the malic acid left in the baked fruit, so the pairing stays lively instead of heavy. Serve it cool, in small glasses.

Vin Santo del Chianti Classico DOC: Trebbiano and Malvasia aged in small sealed barrels give walnut, dried apricot and caramel. That nutty depth echoes the caramelised glaze on top of the cake rather than contrasting with it. Pour a small glass, served cool, and let the cake take second place to the wine on the palate for a moment, since the two are equal partners here.

Moscato d'Asti DOCG: At around 5.5 percent alcohol, with a light frizzante lift, it will not bury a cake that is not very sweet. Elderflower and white peach sit beside apple and lemon zest, and the bubbles lift the melted butter off the tongue. It is the everyday choice for an afternoon table and asks nothing of the cook.

Storage & Reheating

Kept whole at cool room temperature under a cloth, the cake is at its best between 12 hours and 3 days after baking. Do not refrigerate it whole, because cold firms the butter in the crumb and turns the exposed apple leathery. Once cut, press parchment against the cut face. Beyond 3 days, wrap it in parchment and foil and refrigerate for up to 5 days more, then bring it to room temperature for an hour.

To refresh a wedge, warm it for 10 minutes in a 300°F (150°C) oven, uncovered. Wrapped wedges freeze for 2 months, and the whole cake freezes as well if wrapped twice. Thaw them wrapped at room temperature for 2 hours, then warm as above. Never microwave a slice, because the fruit heats faster than the crumb and leaves a scalding centre inside a rubbery edge.
