Fat used in cooking (4)

I think it could be either:

suet

lard

'fat used in cooking' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for suet that I've seen before include "Hard fat from beef and sheep" , "Solid fat used in cooking" , "Hard animal fat used in cooking" , "Hard white fat on sheep's kidneys" , "Hard fat in cattle and sheep" .)

I've seen this clue in The Mirror and the Evening Standard.
