Strong drink and salmon consumed by everyone (7)
I believe the answer is:
alcohol
'strong drink' is the definition.
(thesaurus)
'salmon consumed by everyone' is the wordplay.
'salmon' becomes 'coho' (type of salmon).
'consumed by' is an insertion indicator.
'everyone' becomes 'all' (I've seen this before).
'coho' placed within 'all' is 'ALCOHOL'.
'and' is the link.
(Other definitions for alcohol that I've seen before include "Strong drink" , "I could get you pickled" , "lager, perhaps" , "John Barleycorn" , "Drug" .)
