Paste hairs, as ordered (7)
I believe the answer is:
harissa
'paste' is the definition.
(I have seen 'hot paste' mean 'harissa' so perhaps 'paste' could also mean 'harissa')
'hairs as ordered' is the wordplay.
'ordered' indicates anagramming the letters.
'hairs'+'as'='hairsas'
'hairsas' is an anagram of 'HARISSA'.
(Other definitions for harissa that I've seen before include "Hot paste used in North African cuisine -- ass hair (anag)" , "Spicy sauce" , "Hot North African sauce" .)
