Does it involve mixing rice with some peas? (6)
I believe the answer is:
recipe
'does it involve' is the definition.
I can't judge whether this defines the answer.
'mixing rice with some peas?' is the wordplay.
'mixing' is an anagram indicator.
'with some peas?' becomes 'pe' (I am not sure about this - if you are sure you should believe this answer much more).
'rice' is an anagram of 'reci'.
'reci'+'pe'='RECIPE'
Can you help me to learn more?
(Other definitions for recipe that I've seen before include "Pierce (anag) - directions" , "Cooking prescription" , "Directions for cooking the turkey e.g." , "Kitchen instructions" , "Formula for food dish" .)
