Revealed information about cooking accident? (7,3,5)
I believe the answer is:
spilled the beans
'revealed information' is the definition.
I know nothing about this answer so I can't tell whether this works.
'about cooking accident?' is the wordplay.
I cannot quite understand how this works, but
'about' could be 'a' (abbreviation in Chambers) and 'a' is located in the answer.
'accident?' could be 'spill' (I've seen this before) and 'spill' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for spilled the beans that I've seen is " Let the cat out of the bag".)
