Take a look at a typical recipe for Spotted Dick. It's basically a bigass steamed biscuit with raisins in it. Served with a custard sauce or treacle or something, which I guess is where "flavor" enters the equation.
Thank you, no. I'll take my pudding in Butterscotch, and my Dick in, er, uhm...never mind.
