Sorry - just noticed this one. So I'm too late with the answer but have you tried making Italian meringue? It's made with sugar syrup, so as you melt it, you can use any sugar.
It's supposed to be really tricky, but there are loads of demonstrations on Youtube. This one is American, but he does go into lots of detail to prevent failure:

Have any of you got all electric cars? Pros and cons please.
