Seafood from Bali cooked in cabin (7)
I believe the answer is:
halibut
'seafood' is the definition.
(I know that halibut is a type of seafood)
'bali cooked in cabin' is the wordplay.
'cooked' indicates anagramming the letters.
'in' is an insertion indicator.
'cabin' becomes 'hut' (I've seen this in another clue).
'bali' is an anagram of 'alib'.
'alib' placed within 'hut' is 'HALIBUT'.
'from' acts as a link.
(Other definitions for halibut that I've seen before include "Swimmer" , "Large flatfish, tasty to eat" , "One's scaled" , "Large flatfish used as food" , "Large edible flatfish" .)
