Combine 1 1/2 cups of the milk, egg yolks, and sugar in a double boiler. Cook slowly until mixture thickens. Meanwhile, melt chocolate with the other 1/2 cup of milk. Add to thickened milk-egg-sugar mixture. Cool. Add cream. Chill mixture 4 hours before making ice cream.

To add candies, chocolate chips, etc, use about 1 1/2 cups, added in the last few minutes of making the ice cream. To make cookie dough ice cream, when making cookie dough, separate out a portion of the mixture to make without eggs to use in your ice cream.
