£10 brought up for cheesemaker (6)
I believe the answer is:
rennet
'cheesemaker' is the definition.
(substance used when making cheese)
'ps10 brought up' is the wordplay.
'ps10' becomes 'tenner' (I've seen this before).
'brought up' is a reversal indicator (down clues only).
'tenner' back-to-front is 'RENNET'.
'for' acts as a link.
(Other definitions for rennet that I've seen before include ""This has turned the milk!"" , "Cheese-maker's substance" , "Substance used to curdle milk for cheese-making" , "Cheese-making curdler" , "what you need to make cheese" .)
