Chocolate Ice Cream Candy

Ingredients

Directions

Cook the candy

  1. In a saucepan, combine the butter, cream of tartar, and chocolate.

  2. Boil the mixture (except for the butter) for 10 minutes.

  3. Add the butter; the mixture will froth and double in size.

  4. Continue boiling until it reaches a soft crack stage.

  5. Pour the mixture onto a well-greased plate or slab.

Knead and flavor

  1. Knead in the powdered chocolate.

  2. Once cool enough, pull the candy and flavor with vanilla while working.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Adds fat for richness and a smooth, tender bite in the finished candy.
Chocolate
Supplies the main chocolate flavor and fat that give the candy its body.
Cream of tartar
Acidifies the sugar mixture, helping prevent crystallization for a smoother texture.

The step that matters

Boil until the soft crack stage. The mixture must reach the soft crack stage, where enough water has evaporated from the sugar syrup. Stopping early leaves the candy soft and sticky, while going too far makes it hard and brittle.
