I did it in the thermomix, but you can do it on the stove top you just have to stir it lots, so it's actually not so easy without a whizz bang machine.

I used 1500ml milk, 200ml cream, 190 g white sugar, and 60g dark sugar, 1/2 tsp bicarb. Next time I'll go all white sugar.

I cooked it at 110 degrees for 50 minutes.

There are stove top recipes as I have seen them. David Lobovitz has a really easy way of doing it in the oven in a pie dish with condensed milk (by pouring it into the dish).
