Italian Modena Stuffed Trotter with Lentils | Zampone con Lenticchie
Updated: Oct 24
Zampone con lenticchie is the dish Italy eats when the year turns. On the thirty first of December a fat glossy sausage cased in the boned foreleg of a pig is lifted out of its water, sliced thick and laid over lentils, because lentils look like small coins and the year ahead is supposed to be a prosperous one. It is superstition, and nobody skips it.
This is not really a sausage recipe. The zampone is bought, not made: only a handful of Modenese producers still bone the foreleg by hand and stuff it with the lean pork, jowl, rind and spices the IGP allows. Your work is the cooking, and the cooking is all restraint: water that never boils, skin pricked first, no salt near the pot.
The lentils have their own discipline: small mountain lentils go into the pan dry, with no soaking, and the salt arrives only at the end. What follows is the version served in Modena on New Year's Eve, skin gelatinous, filling moist, lentils whole but soft.
Yield: 6 servings. Soak, raw only: 12 hours. Prep: 30 minutes. Cook: 4 hours for raw, 40 minutes for precooked. Rest: 15 minutes. Difficulty: intermediate. Course: secondo. Region: Emilia Romagna, Modena.
The Story
Modena tells the story like this. In 1511 the papal army of Julius II was camped around Mirandola, a fortress town on the plain north of the city held by the Pico family. There were pigs to slaughter before the enemy took them and no casings left. Somebody in the kitchens of the Pico court boned out a front leg, skin, trotter and claw included, packed the chopped meat into that pocket and sewed it shut. The zampone exists because a cook ran out of intestine and refused to waste a pig.
Legend or not, the technique is Modenese and old, documented in the city from the sixteenth century onward. By the nineteenth century zampone was Modena's export to the rest of Italy. Zampone Modena IGP sets the boundaries today: foreleg skin as the casing, a filling of lean pork with jowl and rind, and a spice mix led by nutmeg and black pepper.
The confusion with cotechino is worth clearing up, because the filling is nearly the same but the two are not interchangeable. Cotechino goes into a beef or pork casing and comes out plain and cylindrical. Zampone goes into the skin of the foreleg, keeps the shape of the leg and the claw, and that skin is the point: thicker, far richer in collagen, and after hours of slow cooking translucent and gelatinous in a way no ordinary casing becomes.
The lentils are not Emilian at all. They come from the Roman habit of eating something round and coin shaped at the start of a new cycle, and Umbria supplies the good ones. In Modena the slices are just as often laid over purè di patate, the potato taking the fat instead of the pulses.

Preparation
Step 1
Read the label, then soak. A raw zampone, sold salted and firm, needs an overnight soak and three to four hours in the pot; a precooked one, sealed in a pouch and already cooked, needs twenty to thirty minutes to come back to temperature and no soaking at all. The difference is printed on the wrapper as crudo or precotto. To soak a raw one, cover it with cold water in a deep bowl and refrigerate for twelve hours, changing the water two or three times: this draws out part of the curing salt and rehydrates the skin so it stretches instead of splitting when the filling expands.
Step 2
Prick the skin, then wrap it. Puncture the skin in twenty or thirty places with a fine needle, especially at the fat near the joint. Fat renders and steam builds inside the casing and the pressure has to go somewhere: pricked skin lets it seep out slowly, unpricked skin bursts and the filling unravels into the water. Then roll the leg in a double layer of cheesecloth and tie it at both ends and around the middle.
Step 3
Cook a raw zampone. Lower it into a tall narrow pot, cover with cold unsalted water by 2 inches (5 cm), add the bay leaves and peppercorns and bring it up slowly. The moment the first bubbles break, drop the heat until the surface only shivers, around 180°F to 190°F (82°C to 88°C), and hold it there for 3 to 4 hours. Never let it boil: a boil outruns the pinholes, tears the casing and drives out the fat so hard the filling finishes dry. A precooked zampone is only warmed, sealed in its pouch in water at a bare simmer for 20 to 30 minutes by the weight on the packet, since twenty extra minutes just squeezes the filling.
Step 4
Start the lentils 50 minutes before service. Rinse them and pick out any stones, but do not soak them: Castelluccio and Colfiorito lentils are thin skinned, cook from dry in half an hour and split if soaked. Warm the olive oil over medium low heat, render the pancetta for 3 minutes, then add the onion, carrot, celery and garlic and sweat them 8 to 10 minutes until soft and translucent with no colour, since browning pushes the lentils toward a roasted flavour they do not want.
Step 5
Cook the lentils and salt them last. Stir in the tomato, cook it out for 2 minutes, add the lentils and turn them through the fat, then pour in hot broth to cover by an inch, add the bay leaf and rosemary and simmer uncovered for 25 to 35 minutes, topping up whenever the surface dries. Only when they are tender right through do the salt and pepper go in: salt at the start hardens the skins and the centres stay chalky. Leave the pan just short of soupy.
Step 6
Rest, unwrap and slice. Lift the zampone out with tongs and let it sit on a board for 15 minutes still wrapped, because cutting straight away loses the fat and juice still moving inside it. Cut the twine, unroll the cloth and slice across the leg in rounds about 1/2 inch (1.5 cm) thick with a long sharp knife, drawn through in one movement rather than sawing. Thin slices fall apart and go cold.
Plating
Serve it hot, and treat hot as a structural requirement rather than a preference. Skin and filling are held together by rendered pork fat and dissolved collagen, and both set as the temperature falls. At 150°F (65°C) the slice is glossy and the skin yields under the knife. Twenty degrees lower the same slice is waxy and the fat greasy on the tongue. Warm the plates and do not plate until everyone is seated.
Spoon a bed of lentils into the centre of each warm plate, wet enough to spread a little of its own accord, and lay two or three slices overlapping across them rather than in a fan. Trickle some lentil liquid around the edge, add a thread of raw olive oil and a scatter of parsley. Mostarda di frutta beside the meat is traditional at New Year and cuts the fat effectively.
Professional Technique
The technique of a zampone is pressure management inside a closed bag. The foreleg skin is a sealed vessel packed with ground pork, jowl fat and rind, and when it heats three things expand at once: water turns partly to steam, the fat liquefies and gains volume, and the collagen in the skin contracts before it relaxes. Pricking creates dozens of controlled escape routes, and water held below a simmer keeps the expansion slow enough for those routes to cope.
Two further principles follow. Cooking in unsalted water runs against most meat cookery, but the zampone is already cured to around two percent inside: a salty pot keeps that salt in the filling, while plain water draws a little out over four hours, which is also why the soaking water is changed several times. And the lentils take salt only at the end, because the pectin holding a pulse skin together is stabilised by sodium ions. Salt early and the skins stay firm while the interior goes on absorbing water, which is exactly how you get a lentil split at the seam and chalky in the middle.
Texture and Moisture Control
Two contrasting textures define the plate and both come from collagen. The rind and skin of the zampone are almost pure connective tissue, and between roughly 160°F and 180°F (71°C and 82°C), held for hours, that collagen hydrolyses into gelatin. That is what four hours buys: the skin goes from rubbery and opaque to soft, translucent and faintly sticky on the lip, and the melted gelatin keeps the filling moist from inside even as fat runs out of it.
The lentils are a moisture problem in the opposite direction. Top up with hot broth rather than cold, which stalls the simmer, do not stir hard once they are tender, and finish with visibly more liquid than looks right, because lentils go on drinking as they stand. Hold the zampone whole in its cooking water, covered, not in a low oven where cut surfaces dry within ten minutes, and if a slice waits, spoon hot cooking liquid over it: the gelatin in that liquid sets around the slice instead of drying it.
Professional Mise en Place
Almost nothing here is done to order, which is why the dish suits a crowded New Year's Eve kitchen. The zampone holds a burner for hours but needs no attention beyond a glance at the water, and the lentils finish in the last half hour.

Chef Tips
Buy from a producer rather than off a supermarket shelf, and buy it raw. The gap between a hand boned Modenese zampone and an industrial precooked one is larger than the gap between any two cooking methods, and it sits in the skin. Look for the IGP mark and a leg that still has its claw.
Keep an instant read thermometer in the pot, or dip one in every half hour. Water that looks still can be at 205°F (96°C) in a tall pot. On most domestic burners the smallest ring at its lowest setting, lid slightly ajar, holds the right temperature.
Save the cooking water. Strained and chilled it sets into a dense pork jelly, the best base for the lentils the next day, for tortellini in brodo, or for reheating slices. A cup stirred in at the end gives a depth no carton broth reaches.
If you cannot find Castelluccio or Colfiorito, look for lenticchie di Onano, di Ustica or di Altamura before reaching for large brown lentils, which want a soak and still finish softer and more broken than you want here.
Common Mistakes
Not pricking the skin. The casing bursts in the second or third hour and the filling escapes into the water. Twenty or thirty punctures with a needle is the whole insurance.
Letting the water boil. A boil tears the skin, drives the fat out too fast and leaves the filling crumbly. The surface should barely shiver for the whole cook, at 180°F to 190°F (82°C to 88°C).
Salting the cooking water. The zampone is already cured inside, and a salted pot blocks the exchange plain water encourages. Bay leaves and peppercorns are all that belong there.
Cooking a precooked zampone as though it were raw. Three hours of simmering squeezes a factory cooked zampone dry and grainy. Check the wrapper and give it 20 to 30 minutes at a bare simmer.
Soaking or early salting the lentils. Small mountain lentils cook from dry in half an hour and split into purée if soaked, and salt at the start stabilises the skins, leaving them split outside and chalky within.
Slicing thin, or serving lukewarm. Thin rounds break apart and lose the gelatinous rim of skin. Cut rounds about 1/2 inch (1.5 cm) thick onto warm plates, since fat and gelatin set as the plate cools and a lukewarm slice tastes greasy rather than rich.
Wine Pairing
Lambrusco di Sorbara DOC: The bottle Modena itself opens for this plate. Sorbara is the palest and most acidic of the Lambruschi, and in its secco version sharp red fruit acidity and a fine bubble scrub the palate clean between mouthfuls of gelatinous skin. Serve it at 50°F (10°C).
Lambrusco Grasparossa di Castelvetro DOC: From the hills south of Modena, the fuller and darker of the two. Where Sorbara cuts, Grasparossa pushes back: a light grip of tannin stands up to the fat of the filling instead of rinsing it away, and its blackberry depth meets the earthiness of the lentils. Choose a secco bottling.
Gutturnio dei Colli Piacentini DOC: The Barbera and Bonarda blend from western Emilia, and the frizzante version is the one to look for. Barbera brings a bracing acidity that handles rendered pork fat as well as anything in Italy, Bonarda softens the edges with plummy fruit, and the bitter finish sits well against the rosemary.
Colli Bolognesi Pignoletto DOCG: A dry white for anyone who does not want red with pork, and a genuinely Emilian one. Pignoletto has brisk green apple acidity, a chalky texture from the hills behind Bologna and a bitter almond finish, and its sparkling version does the Lambrusco's job.
Franciacorta DOCG: The metodo classico option and the most elegant way to handle the richness. Time on the lees gives a bready, hazelnut depth that echoes the spiced filling, while the fine mousse and firm acidity lift the fat off the tongue. Stay with brut or extra brut: residual sugar blunts the savoury edge of the meat.
Avoid sweet wines: sugar and pork fat compound each other and the palate has nowhere to go after the second slice. This dish needs acidity, carbon dioxide or tannin, preferably two of the three.
Storage & Reheating
Cooked zampone keeps refrigerated for 3 days, and far better whole than sliced. Leave it in its cheesecloth, put it in an airtight container with a ladle of the strained cooking liquid and refrigerate once cooled. The liquid sets into jelly around the leg and seals the cut surfaces, which is why a whole zampone is almost as good on the second day, while sliced meat stored dry goes grey at the edges within a day.
To reheat, avoid the microwave and the dry oven. Put the slices in a pan with enough cooking jelly or hot broth to come halfway up, cover and warm over the lowest heat for 8 to 10 minutes, turning once, so the gelatin melts back around the meat. The lentils are better on the second day and keep 4 days refrigerated; reheat with a splash of hot broth, stirring gently. Both parts freeze, the zampone whole with some of its liquid for up to 2 months and the lentils in portions for up to 3 months, but never together, since the lentils thaw faster and turn to mush while the meat is still solid.
