With hindsight, produced something cheesy (4)
I believe the answer is:
edam
'something cheesy' is the definition.
(type of cheese)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for edam that I've seen before include "Madeinto popular cheese" , "Cheese made in Holland" , "milk product" , "Yellow cheese with a red covering" , "Netherlands cheese" .)
