  23. Drat, I just bought a cake leveler from Sur la Table… I was going to buy one of the little ones like that, but the sales clerk told me he had one and it was worthless, so he talked me into the big one. It’s big enough for sheet cakes. I’ll have to see what I can do, because this looks too amazing to not make…
