It can be cooked with some canned potatoes (5)
I believe the answer is:
capon
'it can be cooked with some canned potatoes' is the definition.
The definition suggests a singular noun which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for capon that I've seen before include "poultry?" , "Castrated male chicken" , "Castrated bird" , "fowl fattened for pot" , "Castrated cock fattened for eating" .)
