Summary

By mixing a simple ice cream base with dry ice, the mixture freezes rapidly while also becoming lightly carbonated.

Procedure

  1. Place dry ice in a paper bag and crush it into small pieces or powder using a mallet, hammer, or rolling pin.
  2. In a large mixing bowl, combine 2 cups heavy cream, 2 cups half-and-half, 3/4 cup sugar, 2 teaspoons vanilla extract, and 1/8 teaspoon salt. (For chocolate ice cream, stir in 1 cup chocolate syrup.)
  3. Slowly add a little crushed dry ice at a time, mixing thoroughly between additions.
  4. Continue adding dry ice until the ice cream thickens to the desired consistency.
  5. Stir in candy pieces, fruit, or flavorings if desired.
  6. If the ice cream is too hard, let it warm slightly before eating. Store leftovers in the freezer.
