Skin duck and roll with some minced spice (5)
I believe the answer is:
cumin
'spice' is the definition.
(cumin is a spice)
'skin duck and roll with some minced' is the wordplay.
I cannot quite understand how this works, but
'and' could be 'n' (common abbreviation for 'and') and 'n' is found within the answer.
'with' could be 'cum' ('with' in Latin) and 'cum' is present in the answer.
A single letter 'i' remains 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 cumin that I've seen before include "Spice used in chilli and curry powder" , "Curry powder ingredient" , "Spice seeds" , "Aromatic seeds used in cooking" , "Culinary spice" .)
