 If you look back at the history of cakes, I mean, all cakes were yeasted cakes, right? Before we had artificial leaveners around 1820 or 30. Right. So the history, if you look at British baking, they have and still have yeasted desserts. And those probably worked out well because yeast would make things nice and light. The next type of cake before you got to the standard yellow cake was a sponge cake.
