A sort of tripe provided stimulation for diner (8)

I believe the answer is:
aperitif
'stimulation for diner' is the definition.
I can't judge whether this definition defines the answer.
'a sort of tripe provided' is the wordplay.
'sort of' indicates anagramming the letters.
'provided' becomes 'if' (eg 'provided it's sunny' means 'if it's sunny').
'tripe' with letters rearranged gives 'perit'.
'a'+'perit'+'if'='APERITIF'
Can you help me to learn more?
(Other definitions for aperitif that I've seen before include "What's drunk before a meal?" , "Alcoholic drink to whet the appetite" , "Pre-meal appetiser" , "wine, possibly, before meal" , "Pre-dinner drink" .)
