Explosive delicacy at children's parties (5)
I believe the answer is:
jelly
'explosive delicacy' is the definition.
'jelly' can be an answer for 'delicacy' (jelly is a kind of delicacy). I'm not certain of the 'explosive' bit.
'children's parties' is the wordplay.
I cannot really understand how this works, but
'parties' could be 'll' (two L's - L can mean the Labour Party) and 'll' is found within the answer.
This explanation may well be incorrect...
'at' acts as a link.
Can you help me to learn more?
(Other definitions for jelly that I've seen before include "Gelatinous pudding" , "Clear dessert" , "Fruit-flavoured dessert" , "Aspic" , "-- and ice cream" .)
