How do you make your cheese cake with a sponge bottom and how do you make the sponge.I know! There are all kinds of recipes out there these days for pretty much anything. I'm just not a big fan of alcohol, for the most part, and I really hate it in any kind of baked goods. But if somebody was coming for dinner and I knew they liked kirsch in their Black Forest Cherry Cake, I would certainly buy it and make the cake the way it should be made. (But I probably wouldn't eat any of it)
As for cake flour, you can sub all-purpose flour. Just for every cup of AP flour you use, remove 2 tablespoons of the flour from each cup. That's a pretty good ratio for all-purpose versus cake. I keep cake flour on hand because there are quite a few recipes I have that use it. I also have pastry flour, from King Arthur. Their cake flour and their pastry flour are both really good. Swan makes a really good cake flour and I've used it....it's in our grocery stores, so easier to find.
I use a sponge cake now as a base for my cheesecakes. Some of them are chocolate, some are regular vanilla. Rick seems to like them more so than a regular graham cracker base. (I don't eat cheesecake either, but Rick loves the stuff.)
