Money required for cheese ingredient to be sent over (6)
I believe the answer is:
tenner
'money' is the definition.
(slang for UK ten pound note)
'cheese ingredient to be sent over' is the wordplay.
'cheese ingredient' becomes 'rennet' (curdled milk used in cheese).
'to be sent over' shows that the letters should be reversed in order.
'rennet' in reverse letter order is 'TENNER'.
'required for' acts as a link.
(Other definitions for tenner that I've seen before include "Monetary note" , "little money" , "A 10 pound note (colloq.)" , "British note" , "Note - sounds like singer" .)
