Cheese in bed eaten by educated woman? (7)
I believe the answer is:
ricotta
'cheese' is the definition.
(I know that Ricotta is a type of cheese)
'bed eaten by educated woman?' is the wordplay.
'bed' becomes 'cot' (cot is a type of bed).
'eaten by' indicates putting letters inside (inserted letters get eaten).
'educated woman?' becomes 'rita' (ref to play and film Educating Rita).
'cot' put inside 'rita' is 'RICOTTA'.
'in' acts as a link.
(Other definitions for ricotta that I've seen before include "Ital. cheese" , "Soft white cheese used in Italian cooking" , "Italian 4 across" , "One soft cheese" , "Read the riot act about the cheese" .)
