Noted price change of interest to cooks (6)
I believe the answer is:
recipe
'change of interest to cooks' is the definition.
I can't judge whether this definition defines the answer.
'noted price' is the wordplay.
I cannot really understand how this works, but
an anagram of 'price' is 'recip' which is present in the answer.
A single letter 'e' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for recipe that I've seen before include "This will explain how to cook" , "Kitchener's instructions" , "Method for cooking" , "method for achieving success" , "Ingredient list" .)
