Scottish dish tasted by convict? (8)
I believe the answer is:
porridge
'scottish dish' is the definition.
'porridge' can be an answer for 'dish' (porridge is a kind of dish). I am not certain of the 'scottish' bit.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for porridge that I've seen before include "Breakfast dish of boiled oatmeal" , "Possibly breakfast - time in prison" , "Breakfast cereal dish" , "Cooked meal (served in prison?)" , "Look in the GPO drier for breakfast" .)
