Like pap, it's not hard to eat (3)
I believe the answer is:
bap
'like pap' is the definition.
The definition suggests a singular noun which matches the answer.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for bap that I've seen before include "Large soft bread roll" , "Big roll" , "A soft flat bread roll" , "Flattish bread roll" , "Large flat round roll" .)
