What's good in dish with pastry covering? (6)
I believe the answer is:
pigeon
'covering?' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'what's good in dish with pastry' is the wordplay.
'what's good' becomes 'g' (abbreviation).
'in' is an insertion indicator.
'dish' becomes 'pie' (I've seen this before).
'with' means one lot of letters go next to another.
'pastry' becomes 'on' (I can't justify this - if you can you should believe this answer much more).
'g' put within 'pie' is 'pige'.
'pige'+'on'='PIGEON'
(Other definitions for pigeon that I've seen before include "Homing bird" , "Racing bird of town and wood" , "See 5" , "birdie" , "Short-legged bird" .)
