The pastry business? (8)
I believe the answer is:
turnover
This clue might be a double definition.
'the pastry' is the first definition.
(turnover is a kind of pastry)
'business?' is the second definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
Can you help me to learn more?
(Other definitions for turnover that I've seen before include "sales of > pastry?" , "Amount of money passing through a business" , "Takings" , "patisserie product" , "Folded pie" .)
