Foie Gras Terrine with Sauternes

Separate the two lobes of each foie gras. Working with slightly warm hands, gently open each lobe and locate the main branching vein network — use the back of a small spoon or your fingers to trace and lift the veins free without tearing the flesh. Remove all visible veins from both lobes. Reshape each lobe gently with your palms.

Combine the salt, white pepper, curing salt (if using), nutmeg, and sugar. Dust this cure evenly over all surfaces of the lobes. Place in a shallow dish, pour over the Sauternes and Armagnac, and turn once to coat. Cover tightly and refrigerate for 48 hours, turning the lobes once at the halfway point.

Remove the foie gras from the refrigerator 30 minutes before cooking. Preheat your oven to 100°C (fan 80°C or 210°F) and bring a kettle of water to a boil, then allow it to cool to approximately 80°C.

Pack the marinated lobes tightly into a 500 ml terrine mould, smooth lobe facing down first, pressing firmly to eliminate air pockets. Pour any remaining marinade over the top. Cover with the terrine lid or a double layer of foil sealed tightly.

Place the terrine inside a deep roasting tray, transfer to the oven, and pour the 80°C water into the tray until it reaches two-thirds of the way up the sides. Poach in the bain-marie for 35 minutes, until a meat thermometer inserted into the centre reads 45–50°C for the traditional silken, barely-set texture — do not exceed 55°C or the fat will fully render out. This traditional French target is well below the temperature at which food-safety guidance considers harmful bacteria reliably eliminated, so this dish is not recommended for pregnant women, young children, elderly people, or anyone with a weakened immune system.

Remove the terrine from the bain-marie. Pour off and reserve the rendered fat from the surface. Cut a piece of cardboard to fit inside the terrine, wrap it tightly in cling film, and place it directly on the foie gras. Weight it with two 400 g tins and refrigerate for at least 6 hours to press and set.

Once pressed, remelt the reserved fat gently and pour a thin sealing layer over the top. Refrigerate uncovered until the fat sets solid, then cover and return to the refrigerator for a minimum of 24 hours before serving — 48 hours produces a more rounded flavour.

To serve, run a thin knife under hot water, wipe dry, and slice the terrine into 1.5 cm portions with one clean downward motion. Lay each slice on a chilled plate, finish with fleur de sel and cracked pepper, and serve with lightly toasted brioche and a glass of chilled Sauternes.
