Relish hearing of choice -- a flower (10)
I believe the answer is:
piccalilli
'relish' is the definition.
(I know that piccalilli is a type of relish)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for piccalilli that I've seen before include "Spicy relish" , "Hot pickle" , "preserve with mustard" , "Relish with chopped pickled cucumbers, green peppers and onion" , "Spicy pickle" .)
