Possibly radish on the counter as requested (2,5)
I believe the answer is:
to order
'as requested' is the definition.
(as in items made to order)
'possibly radish on the counter' is the wordplay.
I cannot really understand how this works, but
'on' could be 'to' and 'to' is present in the answer.
The remaining letters 'order' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for to order that I've seen before include "In fulfilment of an instruction" , "as required" , "In accordance with specification" , "As specified" .)
