Has first person been cooking unorthodox rag with this vegetable? (9)
I believe the answer is:
aubergine
'this vegetable?' is the definition.
(aubergine is a kind of vegetable)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for aubergine that I've seen before include "Vegetarians might order this" , "I agree bun could become a strange vegetable" , "Fruit cooked and eaten as a vegetable" , "Edible plant" , "Moussaka ingredient" .)
