Foie gras — the fattened liver of a duck or goose — is associated in the popular imagination with Parisian luxury. In reality, it is peasant food from Gascony and the Périgord, where farm families have been fattening ducks since at least Roman times (the Romans fattened geese on figs; the word "foie" derives from the Latin "ficatum," meaning "fig-fed"). In southwest France, the entire duck is used: the fattened liver is the most famous product, but the magret (breast), confit (salt-cured and slow-cooked legs), gésiers (gizzards), cou farci (stuffed neck), and rendered duck fat are all essential to the regional kitchen. Nothing is wasted. The duck that produces the foie gras also produces the fat that fries the potatoes sarladaises, the confit that fills the cassoulet, and the gizzards that top the salade périgourdine.
- **Mi-cuit is the benchmark preparation.** Foie gras mi-cuit (half-cooked) — seasoned with salt and pepper, sometimes a splash of Sauternes, cooked in a terrine at 85°C until the internal temperature reaches 55°C, then chilled for 48 hours — is the preparation that maximises flavour and texture. Fully cooked (en conserve) is shelf-stable but denser. Raw (cru) is for searing. - **Temperature control is absolute.** Over 55°C internal, the fat begins to render uncontrollably and the liver collapses into a pool of melted fat. Under 50°C, it remains raw in the centre. The 3–5°C window between perfection and disaster is what makes foie gras terrine one of the most technically demanding cold preparations in French cooking. - **Devein completely.** The network of veins running through the liver must be removed before cooking — they toughen during cooking and leave bitter traces. Deveining a whole lobe without destroying it requires practice and a gentle hand. - **Seared foie gras is a 90-second dish.** A thick slice, seared in a dry, screaming-hot pan for 45 seconds per side. The exterior caramelises while the interior remains creamy. Serve with something acidic — Sauternes reduction, fig compote, apple gastrique — to cut the richness.
