Some of the sloppiest food? (4)
I believe the answer is:
pies
'food?' is the definition.
(pies are a type of food)
'some of the sloppiest' is the wordplay.
'some of' says the answer is hidden in the clue.
'PIES' is hidden in the letters of 'sloppiest'.
(Other definitions for pies that I've seen before include "Dishes baked in pastry-lining" , "Pastries" , "Pastry-topped puddings" , "Tarts" , "food" .)
