Some ricotta-covered pancake (4)
I believe the answer is:
taco
'pancake' is the definition.
(I've seen this before)
'some ricotta-covered' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'TACO' is hidden in the letters of 'ricotta covered'.
(Other definitions for taco that I've seen before include "Filled tortilla roll" , "Mexican food" , "Mexican dish of rolled tortilla with filling" , "Folded and filled tortilla" , "Mexican rolled pancake with a filling" .)
