Breakfast time in jail? (8)
I believe the answer is:
porridge
This might be a double definition.
'breakfast' is the first definition.
(porridge might be eaten for breakfast)
'time in jail?' is the second definition.
'porridge' can be an answer for 'time' (I've seen this before). I am not certain of the 'in jail?' bit.
Can you help me to learn more?
(Other definitions for porridge that I've seen before include "Morning oats" , "Possibly breakfast - time in prison" , "Spell in jail and breakfast food" , "Hot breakfast food" , "Breakfast cereal dish" .)
