Chocolate Sorbet Recipe

1 cup sugar
1/2 cup cocoa powder
1-1/2 cups water
1 tsp vanilla essence
2 tbsp liqueur, such as rum, brandy, Framboise, Kahlua, creme de menthe

Combine the sugar and cocoa powder in a heavy-bottomed saucepan. Gradually mix in the water. Place over medium heat, bring to a simmer, and stir until the sugar dissolves. Increase the heat and bring to a boil. Boil the syrup until it is dark, glossy brown, 1-2 minutes. Pour the mixture into a bowl and stir in the vanilla extract and liqueur of choice. Cover and chill until cold, then freeze.
