Slice of Kashmiri cottage cheese (7)
I believe the answer is:
ricotta
'cheese' is the definition.
(ricotta is a type of cheese)
'slice of kashmiri cottage' is the wordplay.
'slice of' indicates the answer is hidden within the clue.
'RICOTTA' is hidden within 'kashmiri cottage'.
(Other definitions for ricotta that I've seen before include "cheese found" , "One soft cheese" , "cheese, Italian style" , "Cheese - Riot Act (anag)" , "Italian 8 across" .)
