Dessert that may go off, say? (5)
I believe the answer is:
bombe
'dessert' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bombe that I've seen before include "Ice cream frozen in a round mould" , "Sweet" , "Ice-cream dessert" , "like some rounded furniture" , "Dome-shaped dessert, often frozen" .)
