Yes, foie gras is occasionally served “cru,” i.e., raw. One such French preparation, “foie gras cru au gros sel”, is foie sliced thin like prosciutto, and sprinkled with coarse salt. Interesting, says Robert Lauriston, but the flavor and texture are better when it’s cooked.
Soaking the foie in milk and curing with some salt before the raw presentation, changes the texture and character from truly raw, adds JudyAU.
In most French recipes for raw foie, you just keep the liver in the fridge until the last minute, and then slice it with a knife that’s been dipped in warm water. The foie gras is garnished with coarse salt, crushed peppercorns and served with toasty country bread. Only the finest liver is used, says Carswell.
