Get at ship in storm for food (9)
I believe the answer is:
spaghetti
'food' is the definition.
(spaghetti is a kind of food)
'get at ship in storm' is the wordplay.
'in storm' indicates anagramming the letters (I've seen this in other clues).
'get'+'at'+'ship'='getatship'
'getatship' is an anagram of 'SPAGHETTI'.
'for' is the link.
(Other definitions for spaghetti that I've seen before include "2 [PASTA]" , "Pasta made from tight peas" , "Stringed pasta" , "course" , "Pasta twirled around a fork" .)
