Chocolate Ice Cream Candy

Ingredients

Directions

Make the candy base

  1. Boil the sugar, water, and cream of tartar for 10 minutes.

  2. Add the butter; the mixture will froth and double in volume.

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

Shape and finish

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

  2. Knead in the powdered chocolate.

  3. When cool enough, pull the candy on a hook, adding vanilla extract while working.

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

What each ingredient does

Sugar
Forms the bulk of the candy and sets into a firm, brittle structure as it cooks.
Butter
Adds richness and a tender texture to the candy.
Cream of tartar
Acidifies the syrup, helping prevent crystallisation and keeping the candy smooth.
Chocolate
Supplies the chocolate flavour and colour throughout the candy.

The step that matters

Continue boiling until it reaches a soft crack stage. Sugar syrup must reach the correct temperature to set properly. Too little cooking leaves the candy sticky, while overcooking makes it hard and brittle.
