Bulb used in cookery (6)
I believe the answer is:
garlic
'bulb used in cookery' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for garlic that I've seen before include "Strong-tasting bulb" , "Pungent member of onion family" , "something with strong smell" , "Plant used in cookery" , "Bulb used in cooking" .)
