These turned out to be a hot mess. I can see how they could be delicious, but I would definitely need to practice juggling the several components before making these again. I had to take my sugar syrup off the burner a time or two because the egg whites weren't where they needed to be. In the end I had a little layer of gelatin that separated out of the bottom of the 'mallows. After smelling the liquid gelatin and re-reading all the Ps&Qs it was just not appetizing. I ate some of the meringue off the tops but that's only because I went through the trouble to make a caramel swirl for them.
Le sigh...I might make these again when my kitchen is big enough to handle the mess.
