Baker's blunder? (7)
I believe the answer is:
bloomer
This clue could be a double definition.
'baker's' is the first definition.
Both the answer and definition are singular nouns.
Perhaps you can see an association between them that I don't see?
'blunder?' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for bloomer that I've seen before include "that's made with flour!" , "Large slip" , "Stupid mistake" , "Mistake (colloq.), loaf" , "Stupid error (colloq.)" .)
