Though sweet, could it make you go to pieces? (7)
I believe the answer is:
crumble
'go to pieces?' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for crumble that I've seen before include "Break up - fruit dish" , "Type of pudding - disintegrate" , "Break into small fragments" , "Fall to bits; a pudding" , "Gradually disintegrate" .)
