Complex flavonoid initially lacking in curry (8)
I believe the answer is:
vindaloo
'curry' is the definition.
(type of curry)
'complex flavonoid initially lacking' is the wordplay.
'complex' indicates an anagram.
'initially lacking' means to remove the first letter.
'flavonoid' with its initial letter taken away is 'lavonoid'.
'lavonoid' with letters rearranged gives 'VINDALOO'.
'in' acts as a link.
(Other definitions for vindaloo that I've seen before include "takeaway?" , "Highly-spiced Indian curry" , "hot stuff!" , "very spicy" , "burner" .)
