Start of recipe with garlic mayo encompassing very Italian dish (7)
I believe the answer is:
ravioli
'italian dish' is the definition.
(I've seen this before)
'start of recipe with garlic mayo encompassing very' is the wordplay.
'start of' suggests taking the first letters.
'with' is a charade indicator (letters next to each other).
'garlic mayo' becomes 'aioli' (I've seen this before).
'encompassing' indicates putting letters inside.
'very' becomes 'v' (abbreviation).
The initial letter of 'recipe' is 'r'.
'aioli' enclosing 'v' is 'avioli'.
'r'+'avioli'='RAVIOLI'
(Other definitions for ravioli that I've seen before include "Filled envelopes of course" , "Fare" , "Small stuffed pasta" , "Filled form of pasta" , "Stuffed pasta squares" .)
