oh yea for the burning you need a double boiler, what you do is take a large saucepan (as big as you can find) and find another one that will fit inside it, but still has about a 1/2 inch all the way around between the two (i.e. you should be able to just set the smaller one inside the bigger one, and it should be far from 'snug') then you put water in the larger pot, fill it up about half way, take the 2nd pot and push it down as far as it goes in the large one, eliminating excess water (then you need to take out about another 1/4-1/2 cup) this means there's never any dirrect flame on your milk, there is only good ol' heat which is what you want.. the water in the larger pot will boil, heating up the smaller one, you need as much water in it as possible, without it boiling over the sides or into the pot your using to heat the milk mixture in.
