Being an Aussie that has been no where near a Yorkshire pudding, I had to look it up. Seems to basically be a batter made with eggs. Since I'm highly allergic to eggs, I'd have to make this sort of pizza thingy without eggs. So it just becomes a very very very deep dish pizza. I could eat that, just keep me away from the eggs.
Any horrified Yorkshire pudding eaters should enlighten me about what a pudding really is, if Wikipedia lied to me.
