Wow, Joypod,

I'm sorry for your misfortune, especially since splenda is so darn expensive, I'm sorry to say I have never melted splenda before but that's because it usaually will do it, itself.

With that I mean, when for instance I make myself a Hot cup of Herbal Tea, put my splenda in and it fizzles out and disappears. Do you think you can put the recipe up so we could see. Maybe there's another way around it, like heating the butter first and then mixing in the splenda after, while it's hot.

Hope that helps
