Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Ratifia Ice Cream
Ingredients
Directions
Make the custard
In a saucepan, combine cream, milk, sugar, egg yolks, and 2 ounces of ratafias.
Heat gently, stirring until it thickens like custard.
Remove from heat and add lemon juice; let cool.
Freeze and finish
Freeze the mixture until partially set.
Rub the remaining 2 ounces of ratafias through a sieve and add to the frozen mixture.
Stir in the glass of noyau or maraschino and freeze until firm.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Adds richness and fat, giving the frozen ice cream a smooth, creamy texture.
- Egg yolks
- Thicken the custard base as they heat and give the ice cream a richer texture.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream softer when frozen.
- Ratafias
- Provide the almond-like flavour that defines the ice cream.
- Noyau or maraschino
- Adds a concentrated liqueur aroma and flavour to the frozen mixture.
The step that matters
Heat gently and stir until the custard thickens. Egg yolks set at a moderate temperature. Overheating scrambles them into lumps, while underheating leaves the base thin, so the ice cream turns out grainy or runny.

Fit is the average pairing score against cream, milk, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
