Liquid food (4)
I believe the answer is:
soup
'liquid food' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for soup that I've seen before include "Mulligatawny or borscht?" , "Bisque, for example" , "Cock-a-leekie, for example" , "Liquid dish" , "Stolen plate melted down" .)
