Lady taking a minute to cut cheese turnover (6)
I believe the answer is:
madame
'lady' is the definition.
('madame' can be a synonym of 'lady')
'a minute to cut cheese turnover' is the wordplay.
'minute' becomes 'm' (abbreviation).
'to cut' is an insertion indicator.
'cheese' becomes 'edam' (Edam is an example**).
'turnover' says the letters should be written backwards.
'edam' back-to-front is 'made'.
'a'+'m'='am'
'am' placed inside 'made' is 'MADAME'.
'taking' acts as a link.
(Other definitions for madame that I've seen before include "Flaubert novel" , "Book by Flaubert" , "Woman of refinement" , "A French-speaking woman" , "Proprietress of a brothel" .)
