Boiled tripe provided after a preprandial drink (8)
I believe the answer is:
aperitif
'preprandial drink' is the definition.
(I've seen this before)
'boiled tripe provided after a' is the wordplay.
'boiled' indicates an anagram.
'provided' becomes 'if' (**).
'after' is a charade indicator (letters next to each other).
'tripe' anagrammed gives 'perit'.
'perit'+'if'='peritif'
'peritif' after 'a' is 'APERITIF'.
(Other definitions for aperitif that I've seen before include "Alcoholic drink taken before meal" , "Appetising drink" , "Stimulant taken before meal" , "it's served before dinner" , "If pirate may have a drink before dinner?" .)
