Directions

1. In a small saucepan, sprinkle gelatin over 1/2 cup cold milk. Let stand until gelatin softens, about 5 minutes. Cook over low, stirring until gelatin has dissolved (it will feel smooth when rubbed between fingers), about 3 minutes. Add sugar; stir until dissolved. Add remaining cup of milk; cook over low until warm (do not boil), about 2 minutes. Remove from heat.
2. Place chocolate in a microwave-safe bowl; heat on high in 20-second increments, stirring between each, until melted. Add cream cheese to chocolate; using a rubber spatula, stir until uniform in color. Pour cup gelatin mixture into chocolate mixture; stir until smooth. Gradually add remaining gelatin mixture, then salt, stirring until smooth. Divide among four small glasses; refrigerate until firm, at least 2 hours. Serve topped with sour cream, if desired.
