Just had a go at this tonight and it looks good. I've also got a recipe for treacle toffee and was rather surprised to learn that one of the ingredients is vinegar!!
I grew up in Lancs in the 50s and 60s and it was tradition on Bonfire night for the women of the area to make parkin and bring it out to the people gathered round the fire......
and treacle toffee.........
parkin and treacle toffee always remind me of bonfire night..........
