Corn I am cooking with a variety of pasta (8)
I believe the answer is:
macaroni
'variety of pasta' is the definition.
(I've seen this before)
'corn i am cooking with a' is the wordplay.
'cooking with' indicates anagramming the letters (cook can mean to falsify or distort).
'corn'+'i'+'am'='corniam'
'corniam' mixed up with 'a' gives 'MACARONI'.
(Other definitions for macaroni that I've seen before include "Tubed pasta" , "Thin tubes of pasta" , "With which one tube-feeds" , "Slender tubes of pasta" , "2 [PASTA]" .)
