Put the milk and the sugar in a thick-based large pan. Cut the vanilla pod or bean right down the middle from top to bottom and add it to the milk.
Heat until boiling then reduce the heat to low and leave to simmer away for 2h30 to 3 hours. Every so often, stir well with a long wooden spoon. It’s normal that nothing much happens in the first couple of hours, then you’ll see that it does thicken quite quickly towards the end.
Take out the vanilla pod and as soon as the jam becomes caramel-like and coats the back of a spoon nicely, take off the heat and pour into a couple of clean jam jars.
