Flour ma ordered for recipe (7)
I believe the answer is:
formula
'recipe' is the definition.
('formula' can be a synonym of 'recipe')
'flour ma ordered' is the wordplay.
'ordered' indicates anagramming the letters.
'flour'+'ma'='flourma'
'flourma' is an anagram of 'FORMULA'.
'for' acts as a link.
(Other definitions for formula that I've seen before include "Set form of words or mehod" , "Set expression" , "Recipe or list of ingredients" , "Category in motor racing" , "Set of mathematical symbols or recipe" .)
