Food that might be hot or cold from the sea (5)
I believe the answer is:
balti
'food that might be hot' is the definition.
(type of curry)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for balti that I've seen before include "Spicy Indian dish served in a metal pot" , "One-pot curry" , "Pakistani curry dish, originating perhaps in 1970s' Birmingham" , "Style of curry" , "Indian cuisine cooked in two-handled dish" .)
