We poach foie gras in various liquids, each with a different result. We poach foie gras in its own fat—a technique called confit—and serve it whole. This is another high-yield technique. The density of the fat and the foie are similar so the liver cooks without losing any of its fat or absorbing the cooking fat. Cooking it in fat also inhibits oxidation.
We make foie gras carpaccio by cutting thin slices of raw foie gras and spooning some hot truffle juice over them just before serving, in effect, poaching the foie gras à la minute.
