Take in, with the dessert (4)
I believe the answer is:
fool
I believe this is a double definition.
'take in' is the first definition.
('fool' can be a synonym of 'take in')
'the dessert' is the second definition.
(I've seen this before)
'with' is the link.
(Other definitions for fool that I've seen before include "Ass; a dessert" , "Part of 1 25 [KING LEAR]" , "Sweet - kid" , "Hoax" , "Charlie" .)
