Grilling an ocean band (7)
I believe the answer is:
searing
'grilling' is the definition.
(thesaurus)
'an ocean band' is the wordplay.
'an ocean' becomes 'sea' ('sea' can be a synonym of 'ocean').
'band' becomes 'ring' (a ring is a band of metal).
'sea'+'ring'='SEARING'
(Other definitions for searing that I've seen before include "An aromatic liquid; aumbry (anag.)" , "Scorching" .)
