One enthralled by pecan nuts as a party snack? (6)
I believe the answer is:
canape
'a party snack?' is the definition.
(I've seen this before)
'one enthralled by pecan nuts' is the wordplay.
'one' becomes 'a' (a thing is one thing).
'enthralled by' indicates putting letters inside ('enthral' can mean 'capture').
'nuts' indicates an anagram (nuts can mean crazy).
'pecan' with letters rearranged gives 'canpe'.
'a' inserted within 'canpe' is 'CANAPE'.
'as' is the link.
(Other definitions for canape that I've seen before include "Small item of food served with drinks" , "Party snack" , "Small piece of bread or biscuit with savoury spread" , "Tasty morsel, with drinks perhaps" , "Small appetiser" .)
