Pasta recipe? Voila! Introduction to Italian cooking (7)
I believe the answer is:
ravioli
'pasta' is the definition.
(ravioli is a kind of pasta)
'recipe? voila introduction to italian cooking' is the wordplay.
'recipe?' becomes 'r' (abbreviation in medical prescriptions).
'introduction to' says to take the initial letters.
'cooking' is an anagram indicator (cook can mean to falsify or distort).
The initial letter of 'italian' is 'i'.
'voila'+'i'='voilai'
'voilai' anagrammed gives 'avioli'.
'r'+'avioli'='RAVIOLI'
(Other definitions for ravioli that I've seen before include "Fare" , "Filled type of pasta" , "Small stuffed pasta" , "Meat-filled pasta squares" , "(Meat, cheese, etc filled) pasta cases" .)
