Liver rolled tightly in linen and gently poached, preserving the liver's own texture without adding fat, distinct from a terrine's bain-marie method. See Rung 3 above for the gavage debate this chapter states rather than adjudicates.
As tradition built it
Serves 8, as a starter. About 1 hour, plus overnight resting.
Ingredients
- 1 whole foie gras, lobes separated, deveined
- 12 g salt, 3 g pepper (20 g and 5 g per kg) salt, pepper
Method
- Bring the whole foie gras to room temperature, about 30 minutes, separate the lobes, devein carefully, remove any greenish or yellowed patches.
- Season with salt and pepper, wrap tightly in film, rest refrigerated 12 to 24 hours.
- Roll into a tight cylinder in a clean linen cloth.
- Poach gently, fully submerged, in water held at a bare simmer, 75 to 80°C, until just set.
- Chill fully before slicing.
What a modern chef changes
The poaching temperature held with more precision than the traditional water bath allows.
Rung 3
Method
- Poach in a temperature-controlled water bath held at a fixed 76°C, using a probe in the water rather than judging a "bare simmer" by eye, the single highest-leverage change for this dish.
- Chill the rolled torchon under light, even weight rather than free-standing, for a cleaner, rounder final slice.
- Serve with a reduction built per Rung 4, a small Armagnac reduction rather than the more common sweet fruit accompaniment, tying the dish directly back to this chapter's other central ingredient.
