Pancake recipe is not terribly precise (5)
I believe the answer is:
'pancake' is the definition.
(I know that crepe is a type of pancake)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for crepe that I've seen before include "French dish" , "Crinkly material" , "Light fabric; pancake" , "Fabric with a wrinkled surface" , "Crinkled fabric - black armband - thin pancake" .)
