Gruel and bread, not fish and chips, was the staple diet of the unfortunate recalcitrants and ne'er do wells who were detained at Her Majesty's pleasure in Scarborough Jail. Having a pint meant 2 ounces of oatmeal in a pint of water for breakfast and supper; lunch was a pound of bread. Every other day the gruel was sweetened with a small amount of molasses. For those who were "booked in" for more than 21 days, a little bread accompanied the gruel.
For those sentenced to hard labour (breaking rocks in the yard) there was happy hour once a week when they also got a pint of soup!
Strangely for a town renowned for its castle, the prison population were housed on various sites away from the Castle since the 1640s.
