Lasagna cheese (7)
I believe the answer is:
ricotta
'lasagna cheese' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ricotta that I've seen before include "Italian 4 across" , "may come from Italian press?" , "Cheese - Riot Act (anag)" , "Soft white cheese used in Italian cooking" , "Italian curd cheese" .)
