Pair with a sales pitch: nutty stuff! (7)
I believe the answer is:
praline
'nutty stuff' is the definition.
(I know that praline is nutlike)
'pair with a sales pitch' is the wordplay.
'pair' becomes 'pr' (abbreviation).
'with' is a charade indicator (letters next to each other).
'sales pitch' becomes 'line' (line can mean a prepared statement or spiel).
'pr'+'a'+'line'='PRALINE'
(Other definitions for praline that I've seen before include "Filling for chocolates made by boiling nuts in sugar" , "Smooth, nutty chocolate filling" , "nutty dessert" , "Sweet, nutty chocolate filling" , "Sweet made with butter and pecans" .)
