Agree with Shyvas, sticky toffee pudding is lurvvvvvvely. Treacle pudding is a bit... rich/heavy/slightly bitter for me, not sure which part of it bothers me.Lots.
The Christmas pudding looks much tastier than our fruitcake. Sticky toffee pudding sounds really yummy.
Treacle pudding looks good, but the name bothers me. I always picture octopus tentacles when I hear the name. Now, Roly-Poly pudding, that's a great name. It looks like our jelly roll cakes. I spotted a few chocolate ones also.
Oh did you encounter Spotted Dick, which I think would be classed as a pudding although it's not in the name?
