Flower made with flour! (7)
I believe the answer is:
bloomer
This might be a double definition.
'flower' is the first definition.
(I've seen this before)
'flour' is the second definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'made with' acts as a link.
Can you help me to learn more?
(Other definitions for bloomer that I've seen before include "Large slip" , "made by a baker" , "Stupid mistake" , "Big mistake" , "Mistake (colloq.), loaf" .)
