This is the easiest dessert I know - but you need a siphon ( which you can get for 25 quid). You can also serve it on its own, with berries on the side, with tuiles or beside any simple cake.
You need
- 400 ml single cream
- 100 ml milk (if you like a denser consistency just use 500 ml single cream)
- a stick of cinnamon
- peel of a lemon
- three table spoons of sugar
Heat all the ingredients together until it is about to boil. Take if off the heat, let it cool down and put it in the fridge for 30 minutes or so. Just before you are going to serve it, strain the mixture though a colander, put it in the siphon, add two charges of air and serve. I normally put some powdered cinnamon and candied lemon peel on top of it, but it is purely for decoration, so no need to bother.
Kids enjoy being how the siphon works, but be very careful if you let them use itas it works with pressure, so you need to manipulate it with extreme care.
