Neapolitan Ice Cream

Ingredients

Directions

Make the custard base

  1. Heat the vanilla beans in 1 quart of cream to boiling, then let it infuse for 1 hour.

  2. In a bowl, combine the sugar and egg yolks, and beat well.

  3. Gradually add the infused cream to the egg mixture while stirring.

  4. Place the mixture over low heat, stirring continuously until it thickens slightly but does not boil.

  5. Remove from heat, strain the mixture, and cool it.

Freeze

  1. Pour the cooled mixture into a freezing can and freeze until smooth.

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

What each ingredient does

Egg yolks
Thicken the custard and add richness as they set gently over low heat.
Cream
Provides fat that makes the frozen ice cream smooth and creamy.
Sugar
Adds sweetness and lowers the freezing point so the ice cream stays soft.
Vanilla beans
Infused into the cream to give the custard its aroma and flavor.

The step that matters

Heating the custard over low heat. Egg yolks thicken as they warm, but if the mixture boils they can curdle and turn grainy. Stir continuously and stop once it coats a spoon lightly.

Swap the beans

How well each one fits the dish's main ingredients (egg, vanilla, cream, sugar):

  1. Almondfits better
  2. Chestnutfits better
  3. Hazelnutfits better
  4. Beansthe original

Fit is the average pairing score against egg, vanilla, cream, sugar. Candidates are from the same food group and used in at least 100 recipes.
