Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Ingredients
Directions
Make the custard base
Beat the yolks of six eggs with a half cup of powdered sugar.
When very light add four tablespoonfuls of maraschino and one tablespoonful of kirschwasser.
Stand in a basin of hot water over the fire and beat constantly for five minutes. Be careful not to curdle the eggs.
Take from the fire, stand in a basin of ice water and beat until cold.
Finish and fill
Stir in carefully one pint of whipped cream and one teaspoonful of vanilla.
Fill paper cases with the mixture and sprinkle the top with grated and sifted macaroons.
Freeze
Put in a freezer in layers with letter paper between.
Take out dasher, but leave on cover and handle to keep straight. Pack with salt and ice, cork in the lid, cover with a piece of carpet and stand aside.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks are beaten into a light foam that gives the frozen dessert its structure and richness.
- Powdered sugar
- Sweetens the egg yolks and helps them whip into a stable, light foam.
- Whipped cream
- Adds fat and air, giving the frozen mixture a light, creamy texture.
- Maraschino (in the method)
- Adds sweetness and a distinct cherry-like aroma to the mixture.
The step that matters
Heating the eggs over hot water. Egg yolks thicken gently as they warm, but if they get too hot they scramble and curdle. Beat constantly over moderate heat so the custard stays smooth and light.
