Put the all the ingredients into into a large saucepan, bring to the boil and simmer whilst stirring for 3 minutes. Its best to use a spatula so you can keep scraping the sides and bottom of the pan.
Allow to cool so you can comfortably touch the side of the pan.
Pour the mixture into individual dishes (ramekins, wine glasses, espresso cups - it is very rich so a smaller serving is better) and chill in the fridge for at least 3 hours.
Serve with a slice of lemon and a little cream poured on top
