Start by cooking the chestnuts. Lay the chestnuts on their flatter side and cut or score halfway around the outer shell until you get to the flesh of the nut. Put them in a pressure cooker, cover them with water and cook for 10 minutes.
Put the fire off and, as soon as you can handle them without getting burnt, start peeling the chestnuts one by one (do this while still hot or they will be hard to peel). Leave the remaining chestnuts in their cooking liquid while peeling them. You need to remove both the outer and the inner skins. Keep them aside.
Put the brown sugar, water and vanilla extract in a pot and bring to a boil. Add the peeled chestnuts and roughly crush them with a wooden spoon. Cook for a couple of minutes, then put the fire off. Blend until completely smooth.
Enjoy as a spread or as a base for other delicious desserts.
