Little iron supply in pasta (10)
I believe the answer is:
tortellini
'pasta' is the definition.
(I know that tortellini is a type of pasta)
'little iron supply' is the wordplay.
'supply' indicates an anagram (in a supple way).
'little'+'iron'='littleiron'
'littleiron' is an anagram of 'TORTELLINI'.
'in' acts as a link.
(Other definitions for tortellini that I've seen before include "Italian dish" , "Pasta is called for" , "Small filled pasta cases" , "pasta dish" , "Rings for food" .)
