This deliciously creamy chocolate sherbet is exactly what we want to satisfy our chocolate cravings. To make it even more decadent, sprinkle on extra chopped chocolate once the sherbet is ready to serve.
Reserve 1/2 cup of the 8 ounces chopped chocolate; cover and set aside. In a medium saucepan, stir together remaining chopped chocolate, the water, sugar, and whole milk. Bring to boiling, whisking constantly. Boil gently for 1 minute. Remove from heat; stir in vanilla. Cover and chill overnight.
Stir the reserved 1/2 cup chopped chocolate into the chilled chocolate mixture. Freeze mixture in a 1-quart ice cream freezer according to manufacturers directions. Allow to firm up in freezer for 4 hours before serving.
To serve, scoop into small glasses or dishes. If desired, chop the 1 ounce chocolate; sprinkle over individual servings.
