Paella spice (7)
I believe the answer is:
saffron
'paella spice' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for saffron that I've seen before include "Spice from crocuses" , "Fans for, say orange food flavour and colouring" , "Spice from crocus" , "- - Walden" , "Golden yellow" .)
