Tortoni Ice Cream

Ingredients

Directions

Make the custard base

  1. Combine sugar and eggs in a bright copper pan and beat until light.

  2. Add cream, mix well, and heat on low, stirring until hot but not boiling.

  3. Strain the mixture through a fine sieve into a bowl and let it cool, stirring occasionally.

Freeze and finish

  1. Once cold, freeze the mixture like regular ice cream.

  2. When well frozen, add nectarine extract and crushed bitter macaroons.

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

What each ingredient does

Eggs
Thicken the custard and add richness and structure as they set with gentle heat.
Sugar
Sweetens the base and softens the frozen texture, keeping it scoopable.
Cream
Supplies fat that makes the frozen ice cream smooth and rich.
Bitter macaroons
Add crisp almond-like crumbs and a bitter contrast to the sweet base.
Nectarine extract
Provides the main fruity aroma and flavor.

The step that matters

Heating the custard without boiling. Heating the egg and cream mixture gently, stirring until hot but not boiling, keeps the eggs from scrambling and curdling, which would leave the base grainy and uneven.
