Starter of cannelloni in Romania, cooked pasta (8)
I believe the answer is:
macaroni
'pasta' is the definition.
(I know that macaroni is a type of pasta)
'starter of cannelloni in romania cooked' is the wordplay.
'starter of' suggests taking the first letters.
'in' means one lot of letters goes inside another.
'cooked' indicates anagramming the letters (letters cooked into a new form).
The first letter of 'cannelloni' is 'c'.
'romania' anagrammed gives 'maaroni'.
'c' placed into 'maaroni' is 'MACARONI'.
(Other definitions for macaroni that I've seen before include "Pasta in long tubes" , "Pasta for Marciano" , "Pasta variety, eighteenth century dandy" , "Tubular pasta" , "Slender tubes of pasta" .)
