Everyone consuming salmon gets the sauce (7)
I believe the answer is:
alcohol
'the sauce' is the definition.
(thesaurus)
'everyone consuming salmon' is the wordplay.
'everyone' becomes 'all' (all people).
'consuming' indicates putting letters inside.
'salmon' becomes 'coho' (type of salmon).
'all' placed around 'coho' is 'ALCOHOL'.
'gets' is the link.
(Other definitions for alcohol that I've seen before include "John Barleycorn" , "Intoxicating drink" , "To a position aboard" , "Ethanol" , "lager, perhaps" .)
