Lout chewed canapé furiously, having being described as rotund, with orange flesh (10)
I believe the answer is:
cantaloupe
'flesh' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Perhaps there's an association between them I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for cantaloupe that I've seen before include "fruit" , "Small melon with ribbed skin" , "Type of melon" , "Musk-melon" , "Small to medium-sized melon with yellowish flesh" .)
