Hot Chocolate with Máchica

In a spice or coffee grinder, grind the toasted barley to a fine powder. In a small bowl, mix the barley powder with the brown sugar and ground cinnamon.

In a medium saucepan, bring the milk to a boil, then remove it from the heat. Add the chopped chocolate and whisk until it is melted. Whisk in the barley mixture and the salt and cook over moderate heat, whisking, until the hot chocolate is thickened, about 5 minutes. Serve at once.
