Cooking pies, call for flavouring (8)
I believe the answer is:
allspice
'for flavouring' is the definition.
(allspice is a kind of flavouring)
'cooking pies call' is the wordplay.
'cooking' is an anagram indicator (letters cooked up into a new form).
'pies'+'call'='piescall'
'piescall' is an anagram of 'ALLSPICE'.
(Other definitions for allspice that I've seen before include "fragrant plant" , "Aromatic West Indian tree" , "Pimento or Jamaica pepper" , "Dried aromatic fruit from the West Indies" , "Pill case (anag.)" .)
