Produce a large quantity in Switzerland for those making coffee on holiday (5,3)
I believe the answer is:
churn out
'produce' is the definition.
(churning out is a kind of producing)
'a large quantity in switzerland for those making coffee on holiday' is the wordplay.
I cannot really see how this works, but
'quantity' could be 'no' (no. is a kind of quantity) and 'no' is found within the answer.
'switzerland' could be 'ch' and 'ch' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for churn out that I've seen before include "Quickly produce" , "milk ready for collection at farm gate?" .)
