Foie Gras: Sautéed and Terrine

Ingredients

• 500–600 g Grade A duck (canard) or goose (oie) foie gras, fresh, single lobe; refrigerator-cold at all times
• For the sautéed escalope
• 1 tsp fine sea salt, applied at the last moment before cooking only
• ¼ tsp white pepper, ground
• ½ tsp caster sugar, for the sautéed version only
• For the terrine
• 1½ tsp fine sea salt, generous seasoning; applied during marination
• ¼ tsp white pepper, ground
• ½ tsp caster sugar
• 60 ml Sauternes, Armagnac, or port, for marination; Sauternes is the classical choice

Method

1. 1
   Keep the lobe refrigerator-cold throughout all handling. Warm hands will melt its surface fat on contact. Split the lobe along its natural seam and remove the central vein system with a small knife and fingers, working methodically from the central trunk outward. The lobe is ready when no visible vein network remains and the flesh, though slightly ragged, holds together. Proceed immediately to the next step without allowing the lobe to warm.
2. 2
   FOR THE SAUTÉED ESCALOPE — Cut the cold deveined lobe into escalopes of 1.5–2 cm thickness. Score each escalope lightly on one side; this slows initial fat rendering and keeps the escalope flat in the pan. Season with salt, white pepper, and sugar only at the moment before cooking — salt applied in advance draws moisture and causes the surface to steam rather than sear.
3. 3
   THIS IS WHERE THE DISH LIVES OR DIES. Heat a dry pan — no added fat — until it is scorching. Lay the escalopes in without crowding. An immediate, violent sizzle must erupt on contact; if it does not, the pan was insufficiently hot and the escalope will absorb its own rendered fat rather than sear. Do not touch the escalope for 45 seconds. Press gently with a spatula at the 30-second mark: the surface should feel firm, the centre slightly yielding. Turn once and cook for a further 30 seconds. Remove to a warm cloth-lined plate. The window between correctly cooked and collapsed is 15 seconds; the escalope continues to render fat for 30 seconds after leaving the pan.
4. 4
   The correctly cooked escalope is golden-brown on its cut faces — the colour of perfect French toast — and shows a warm pink interior when viewed in cross-section, transitioning to deeper gold at the edges. It has contracted slightly from its raw size but retains clear structural integrity. If the escalope has contracted to half its original diameter, the fat has been expelled and the dish is lost.
5. 5
   A searing escalope produces a smell that is deeply rich, butter-forward, and slightly sweet from caramelising fat, with a subordinate liver note beneath. If the smell shifts to one primarily of burning fat, the surface has passed the Maillard stage into pyrolysis; remove the escalope immediately and assess.
6. 6
   FOR THE TERRINE — Devein the lobe as above. Season generously with salt, white pepper, sugar, and Sauternes or Armagnac. Pack into a terrine mould, pressing firmly to eliminate all air pockets. Marinate overnight in the refrigerator.
7. 7
   Cook the sealed terrine in a bain-marie at 80°C for 20–25 minutes, until the internal temperature of the lobe reaches 45–50°C. The fat that has rendered into the mould should be clear and pale gold, not white and opaque — opaque expelled fat indicates a temperature overshoot and the terrine will be dense and waxy in texture.
8. 8
   Remove from the bain-marie, cool briefly, then press the terrine with a weighted board as for a galantine. Refrigerate for a minimum of 48 hours before slicing. The terrine is ready when it holds a clean, firm slice without crumbling, and the cut face shows an even, pale ivory-gold colour throughout.
