Couldn't wait! I just cut the Key Lime Soap Pie! That was only about 4 hours after making it. The soap heated up, but I just left it out uncovered. I waited until it cooled down before I popped it out of the mold. Never thought I'd be able to cut it that quickly, but it came out great!
Here's a slice.
Super cute! Right now they are about 3.75 oz per slice. Which will probably cure out to 3.5 oz in the end. I think next time though I will add more piping around the edge and less in the center. I like the piping to look more built up along the outside. Yay! OK, now we'll see how well the vanilla white color stabilizer will work as the slices cure.
