Indian food found by cold sea (6)
I believe the answer is:
baltic
'sea' is the definition.
(I know that Baltic is a sea)
'indian food found by cold' is the wordplay.
'indian food' becomes 'balti' (type of curry).
'found by' says to put letters next to each other.
'cold' becomes 'C' (eg on taps).
'balti'+'c'='BALTIC'
(Other definitions for baltic that I've seen before include "water, lots" , "Coming from Tallinn, perhaps" , "Near-landlocked sea of N Europe" , "Almost land-locked sea of Scandinavia" , "Almost land-locked sea of NE Europe" .)
