Homemade Marshmallows

When I was eight or so, I saw a recipe for marshmallows in a cookbook. I thought that sounded really cool so I tried to make it, but results were inedible. What I ended up with was a layer of sugary syrup topped with a layer of watery gelatin. Today I gave it another try and I don't know how this recipe differed from the one I first tried but I imagine I did not actually heat the syrup to the proper temperature and did not drizzle it into the gelatin slowly enough to incorporate it when I was a kid. But today.. success!
