Instructions on record for pie-making (6)
I believe the answer is:
recipe
'instructions' is the definition.
(I've seen this before)
'record for pie-making' is the wordplay.
'record' becomes 'rec' (I've seen this in other clues).
'for' is a charade indicator (letters next to each other).
'making' indicates anagramming the letters.
'pie' anagrammed gives 'ipe'.
'rec'+'ipe'='RECIPE'
'on' acts as a link.
(Other definitions for recipe that I've seen before include "Kitchener's instructions" , "Cook's formula" , "Formula for food dish" , "Kitchen directions" , "Meal instructions" .)
