Coming back to dry fish (6)
I believe the answer is:
turbot
'fish' is the definition.
(turbot is a kind of fish)
'coming back to dry' is the wordplay.
'coming back' is a reversal indicator.
'dry' becomes 'brut' (type of wine).
'to'+'brut'='tobrut'
'tobrut' written backwards gives 'TURBOT'.
(Other definitions for turbot that I've seen before include "Flatfish - trout B (anag)" , "Large brownish European flatfish" , "Large succulent flatfish" , "Expensive flatfish" , "Large food fish" .)
