1 quart (1l) half-and-half or whole milk
8 ounces (230g) bittersweet or semisweet chocolate, finely chopped
4 ounces (115g) milk chocolate, finely chopped
tiny pinch of salt
1/2 teaspoon ground cinnamon

1. Warm about one-third of the half-and-half or milk, with the chopped chocolates and salt, stirring until the chocolate is melted.

2. Whisk in the remaining half-and-half or milk, heating until the mixture is warmed through. Add the cinnamon.

3. Use a hand-held blender, or a whisk, and mix the hot chocolate until it's completely smooth. Serve very warm.
