Mark bringing flower back? This is sweet (6,4)
I believe the answer is:
brandy snap
'this is sweet' is the definition.
(I've seen this before)
'mark bringing flower back?' is the wordplay.
I cannot really see how this works, but
'mark' could be 'brand' (brand is a kind of mark) and 'brand' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for brandy snap that I've seen before include "Crisp ginger biscuit" , "Cookie" , "Crisp, rolled biscuit" , "Cream-filled gingerbread wafer" , "sweet thing" .)
