Foie Gras d'Alsace

Ingredients

• 1 (500–700 g) Whole raw goose foie gras, Grade A, or duck foie gras 400–600 g; free of bruises and bile stains
• For the seasoning and marinade
• 12 g per kg liver Fine salt
• 3 g per kg liver White pepper, ground
• 1 generous pinch Quatre-épices, white pepper, nutmeg, cloves, ginger
• 15 ml Gewurztraminer, one tablespoon; a late-harvest style
• Optional pre-soak
• 500 ml Whole milk, to cover the deveined liver
• To serve
• 4–6 slices Brioche, sliced and toasted
• 1 pinch per plate Fleur de sel

Method

1. 1
   Bring the liver to 10–12 °C — cold enough to be firm, warm enough to be pliable. Separate the two lobes. Locate the main vein and extract the entire venous tree using a small knife and tweezers, pulling gently and continuously to avoid tearing the flesh. Inspect both lobes for green bile stains; any discoloured flesh is removed entirely. The liver is ready when it lies flat and intact, veins absent.
2. 2
   Optional: submerge the deveined liver in cold whole milk and refrigerate for 2 hours to draw out residual blood and any trace of bitterness. Lift, drain, and pat dry with a cloth.
3. 3
   Weigh the liver. Apply 12 g fine salt, 3 g ground white pepper, and a generous pinch of quatre-épices per kilogram of liver. Add one tablespoon (15 ml) of Gewurztraminer. Turn the lobes gently to coat all surfaces evenly. Cover and refrigerate for 12–24 hours. At the end of marination the liver is fragrant with spice and wine.
4. 4
   Pack the marinated lobes into a porcelain terrine mould, pressing firmly to eliminate all air pockets and arranging the larger lobe on the bottom. Smooth the surface flat with a spatula. Cover with the terrine lid or a sheet of foil. The surface should be perfectly level — any cavity will trap steam and compromise the final texture.
5. 5
   This is where the dish lives or dies. Place the covered terrine in a bain-marie and transfer to an oven set at 90–100 °C. Cook for approximately 40–50 minutes, monitoring the internal temperature with a probe thermometer. Remove the terrine from the oven the instant the centre reads 50–55 °C — the ideal is 52 °C, which produces the creamiest, most unctuous result. Exceeding 55 °C renders excess fat and yields a dry, crumbly terrine that cannot be corrected.
6. 6
   Pour off or reserve the pool of golden cooking fat (it is valuable for sautéing). Place a piece of card cut to fit inside the terrine rim, weighted with 500 g, directly on the surface of the foie gras. Refrigerate under this weight for a minimum of 48–72 hours. The terrine is ready when it is firm, cohesive, and the flavours have fully melded — this cannot be rushed.
7. 7
   Remove the terrine from the refrigerator 20–30 minutes before serving so it reaches approximately 16 °C. Slice 1.5 cm thick with a knife dipped in hot water. Serve on toasted brioche with a pinch of fleur de sel. Below 16 °C, both flavour and texture remain muted.
