Why it works: Egg and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Neapolitan Ice Cream
Ingredients
Directions
Make the custard
In a pan, mix the water, egg yolks, and Maraschino liqueur.
Add sugar to taste and place the pan over low heat.
Whisk continuously until the mixture is almost boiling.
Remove from heat and continue whisking until it foams.
Freeze and serve
Pour the mixture into a Neapolitan ice box.
Surround the box with small pieces of ice mixed with coarse sea salt for 4-5 hours.
Dip the box in warm water for a second. Remove the cover. Let it slide out.

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.
