Item cooked with curry mainly? (8)
I believe the answer is:
turmeric
'item cooked with curry mainly?' is the definition.
I can't judge whether this defines the answer.
'item cooked with curry mainly?' is the wordplay.
'cooked with' is an anagram indicator.
'mainly?' means to remove the last letter (I've seen 'mainly' mean this).
'curry' with its last letter taken off is 'curr'.
'item' mixed up with 'curr' gives 'TURMERIC'.
(Other definitions for turmeric that I've seen before include "It's hot" , "kitchen ingredient" , "ginger relative" , "Yellow spice used in curry" , "Yellow aromatic powder used in cooking" .)
