Cheese in bed, eaten by woman (7)
I believe the answer is:
ricotta
'cheese' is the definition.
(ricotta is a kind of cheese)
'bed eaten by woman' is the wordplay.
'bed' becomes 'cot' (cot is a kind of bed).
'eaten by' is an insertion indicator.
'woman' becomes 'rita' (**).
'cot' placed inside 'rita' is 'RICOTTA'.
'in' is the link.
(Other definitions for ricotta that I've seen before include "Italian 8 across" , "One soft cheese" , "Sheep's milk cheese" , "dairy produce" , "Soft white cheese used in Italian cooking" .)
