2 1/4 cups water
1 cup sugar
3/4 cup unsweetened cocoa powder
pinch of salt
6 ounces bittersweet chocolate, finely chopped
1/2 teaspoon vanilla
1 1/2 tablespoon dark rum
In a saucepan whisk together 1 1/2 cups water with the sugar, cocoa powder, and the salt. Bring to a boil while whisking constantly. Remove from heat after 45 seconds of boiling. Stir in the chocolate until melted. Add the vanilla, remaining 3/4 cup water and rum. Stir together. Transfer mixture into a blender and blend for 15 seconds. Chill thoroughly in the fridge.
Once very cold, pour into your ice cream maker and freeze according to manufacturers instructions. Serve and enjoy!
