At a fancy price, the key to a tasty dish? (6)
I believe the answer is:
recipe
'a tasty dish?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'at a fancy price the key' is the wordplay.
'at' says to put letters next to each other.
'a fancy' is an anagram indicator.
'the key' becomes 'e' (I've seen this in other clues).
'price' is an anagram of 'recip'.
'recip' next to 'e' is 'RECIPE'.
'to' is the link.
Can you help me to learn more?
(Other definitions for recipe that I've seen before include "Directions for cooking the turkey e.g." , "Meal instructions" , "Cookery instructions" , "Instructions on how to cook" , "Instruction for cooking" .)
