Cooked for culinary tool White (9)
I believe the answer is:
alabaster
'white' is the definition.
(alabaster is a kind of white)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for alabaster that I've seen before include "Type of gypsum" , "Stone often used for carving" , "medium of sculpture" , "White mineral used for carving" , "White or translucent mineral" .)
