Neapolitan Ice Cream

Ingredients

Directions

Make the custard

  1. In a pan, mix the water, egg yolks, and Maraschino liqueur.

  2. Add sugar to taste and place the pan over low heat.

  3. Whisk continuously until the mixture is almost boiling.

  4. Remove from heat and continue whisking until it foams.

Freeze and serve

  1. Pour the mixture into a Neapolitan ice box.

  2. Surround the box with small pieces of ice mixed with coarse sea salt for 4-5 hours.

What each ingredient does

Egg yolks
Emulsify and thicken the custard, giving the ice cream its rich, smooth body.
Sugar
Sweetens the mixture and lowers the freezing point so the ice cream stays softer.
Maraschino liqueur
Adds aroma and flavour and lowers the freezing point slightly for a softer texture.

The step that matters

Whisking the custard over low heat. Egg yolks set when overheated and can curdle into lumps. Whisking constantly over low heat keeps the custard smooth and thickened, stopping just short of boiling.
