Curry ingredient in a can (4)
I believe the answer is:
aloo
'curry ingredient' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'a can' is the wordplay.
'can' becomes 'loo' (slang).
'a'+'loo'='ALOO'
'in' is the link.
Can you help me to learn more?
(Other definitions for aloo that I've seen before include "Indian potato" , "Spud" , "chat in Mumbai perhaps" , "chat in India perhaps" , "Potato dish" .)
