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 as they set on gentle heating and enrich its texture.
Cream
Adds richness and fat, giving the frozen custard a smooth, creamy texture.
Ratafia biscuits
Provide almond flavour and a crumbly texture throughout the custard.
Sugar
Sweetens the custard and softens the texture of the frozen mixture.
Maraschino liqueur
Adds aroma and flavour, and its alcohol keeps the frozen custard softer.
Whipped cream
Adds air and lightness, making the frozen dessert less dense.

The step that matters

Passing the custard through a fine sieve after cooking. Straining removes any bits of overcooked egg and crushed biscuit, so the custard stays smooth; cooking over medium heat only until it thickens prevents the yolks from scrambling.
