Make a mistake with popular bun for toasting (6)
I believe the answer is:
muffin
'toasting' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'make a mistake with popular bun' is the wordplay.
I cannot really understand how this works, but
'mistake' could be 'muff' (muff is a kind of mistake) and 'muff' is present in the answer.
'popular' could be 'in' ('in' can mean trendy) and 'in' is found in the answer.
No letters remain.
This explanation may well be incorrect...
'for' acts as a link.
Can you help me to learn more?
(Other definitions for muffin that I've seen before include "Flat round cake, eaten toasted and buttered (6)" , "Round yeast dough bun" , "Type of cake" , "Toasted, spongy bread roll" , "Thick roll, usually toasted" .)
