Produce good food in Derbyshire (8)
I believe the answer is:
bakewell
'food in derbyshire' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'produce good' is the wordplay.
'produce' becomes 'bake' (I can't explain this - if you can you should give a lot more credence to this answer).
'good' becomes 'well' (synonyms).
'bake'+'well'='BAKEWELL'
Can you help me to learn more?
(Other definitions for bakewell that I've seen before include "Town in Peak District" , "Town known for tarts" , "Pastry from Derbyshire" , "town in Derbyshire" .)
