Italian food in shop a starter (5)
I believe the answer is:
pasta
'italian food' is the definition.
(type of Italian food)
'in shop a starter' is the wordplay.
'in' says the answer is hidden in the clue.
'PASTA' is hidden in the letters of 'shop a starter'.
(Other definitions for pasta that I've seen before include "Dried flour paste for making Italian food" , "Spaghetti, ziti, fusilli, for example" , "Eg, lasagne" , "The stuff of spaghetti, macaroni etc" , "Dried flour paste used in cooking Italian dishes" .)
