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 anagramming the letters.
'initially lacking' means to remove the first letter.
'flavonoid' with its first letter taken away is 'lavonoid'.
'lavonoid' anagrammed 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" .)
