Dessert following starter of scallops (6)
I believe the answer is:
afters
'dessert' is the definition.
(I've seen this before)
'following starter of scallops' is the wordplay.
'following' becomes 'after' (I've seen this before).
'starter of' says to take the initial letters.
The initial letter of 'scallops' is 's'.
'after'+'s'='AFTERS'
(Other definitions for afters that I've seen before include "Sweet course" , "Strafe with desserts" , "Dessert (colloq.)" , "Pud" , "food for pudding" .)
