I've made several of these recipes, and have generally gotten terrible results. And the quantity each recipe says it makes is way off on the ones I tried.It appears as though the author has taken one recipe and then extrapolated what *might* work in other situations--without actually testing the formulas. I'm not even talking about the "variations" that help bolster the "500 cupcakes" claim. The basic recipes simply don't work well.So this is really more of a theoretical cookbook, and unfortunately the theory doesn't hold up in real life.The pictures, however, are lovely.
