What it is

Crépine is the omentum, the fat-laced membrane that hangs over a pig's stomach; one animal yields a single sheet, which is why butchers ration it. English and French both borrow the word from birth — the caul, la coiffe, that some babies arrive wearing, once sold to sailors as insurance against drowning.

In the kitchen

Soak it in tepid water, sharpened with a splash of vinegar if it is heavily salted, until it unfolds by itself — pull at it cold and it tears. Wrap in one layer only: two and the fat cannot all render, and you get a greasy skin instead of a crisp one.
