Food items possibly bolted (4)
I believe the answer is:
nuts
'food' is the definition.
(I know that nuts is a type of food)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for nuts that I've seen before include "Fruit - bats" , "Mad (slang)" , "Mad; fruit" , "Eccentric; coal lumps" , "Crackers - or what crackers are required for?" .)
