Pot to taste in food store (6)
I believe the answer is:
pantry
'food store' is the definition.
(I've seen this before)
'pot to taste' is the wordplay.
'pot' becomes 'pan' (I've seen this before).
'to taste' becomes 'try' ('try' can be a synonym of 'taste').
'pan'+'try'='PANTRY'
'in' is the link.
(Other definitions for pantry that I've seen before include "Small room or cupboard for storing food" , "Food store" , "Kitchen storeroom" , "Type of larder" , "Small storeroom for food etc" .)
