Fermentation & Preservation

Confit (Charcuterie)

Also: confit, duck confit, confit de canard, pork confit

A French preservation technique in which meat — classically duck or pork — is slow-cooked and then stored submerged in its own rendered fat.

/kon-FEE/French: 'confire' (to preserve); from Latin 'conficere' (to put together, to prepare). The technique predates refrigeration as a cornerstone of Gascon peasant larder management.

Definition

Confit (charcuterie sense) is a two-stage fat-based preservation method. In the first stage, seasoned meat — most commonly duck legs, pork shoulder, or goose — is cured under salt and aromatics (thyme, bay, garlic, black pepper) for 12–48 hours to draw out moisture and season deeply. In the second stage, the meat is cooked at very low temperature (typically 82–93°C / 180–200°F) submerged in its own rendered fat until fully tender and the connective tissue has dissolved, usually 2–6 hours depending on the cut. The low, even heat prevents the fat from frying the meat; instead it conducts heat gently, producing collagen-rich, impossibly supple flesh. Once cooked, the meat is packed into crocks or jars, and the strained fat is poured over to seal out oxygen and form an anaerobic barrier. Stored below 10°C, properly sealed confit keeps for several weeks to months. The preservation mechanism is threefold: reduced water activity from the initial salt cure, anaerobic storage eliminating aerobic spoilage organisms, and the antimicrobial properties of the fat layer. To serve, the confit is seared or roasted to crisp the skin, the fat reserved for cooking pommes sarladaises or sautéed vegetables. Confit differs from braising in that no water or stock is present; the fat is not absorbed and acts purely as a heat-transfer and preservation medium.

In use

The duck legs had been confited two weeks earlier and stored in their own fat; pulled from the crock and crisped in a hot pan, they emerged mahogany-skinned and yielding at the bone.

Notes

Temperature precision

Modern sous vide confit at 64–68°C produces a pasteurized, silky result without ever reaching traditional oven temperatures; the fat is then poured over for storage. This extends the technique to sous vide practitioners while maintaining the same preservation principles.

Fat reuse

Confit fat improves with each successive batch, absorbing flavor from the meat and aromatics. It can be strained and reused multiple times before the solids accumulate enough to compromise quality.

Beyond duck and pork

The confit method extends to garlic (whole cloves submerged in olive oil at low heat), tuna (ventresca-style), and vegetables, though these lack the charcuterie preservation character and are better understood as confiture preparations.
