Cooked meat from pasty’s insides (5)
I believe the answer is:
roast
'cooked meat' is the definition.
(I've seen this before)
'from pasty's insides' is the wordplay.
'from' becomes 'ro' (I can't justify this - if you can you should give a lot more credence to this answer).
'insides' means to look at the middle letters (I've seen 'inside' mean this).
The middle of 'pasty' is 'ast'.
'ro'+'ast'='ROAST'
Can you help me to learn more?
(Other definitions for roast that I've seen before include "Cooked like chestnuts tonight" , "Traditional dinner" , "Cooked joint" , "Cook, eg, joint of meat" , "Oven joint" .)
