Yorkshire pudding isn't the only savoury pudding.
Haggis, in the words of the Scottish national bard, Rabbie Burns, is the:
"Great chieftain o' the puddin' race!"
Otherwise, I'm with Rat. Pudding, to me, is just another term for dessert. Steamed puddings are made in a pudding basin (shaped like a mixing bowl), and are usually a mixture of dried fruit, sugar, flour, fat, fruit peel, eggs or some variation thereon. The basin is covered with greaseproof paper, tied with string, and then to cook, you steam it - ie, put the basin in a pan of boiling water over the stove and boil for an hour or longer.
