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 over low heat, combine cream, milk, sugar, egg yolks, and 2 ounces of ratafias.
Cook gently until thickened like custard, then remove from heat and stir in lemon juice.
Let the mixture cool, then freeze it.
Finish and serve
Once frozen, rub the additional 2 ounces of ratafias through a sieve and mix in with the frozen mixture.
Add the noyeau or maraschino if desired.

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
- Egg yolks
- Thicken the custard base and add richness as they set gently over low heat.
- Cream
- Provides fat for a rich, smooth texture that resists large ice crystals.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream softer.
- Ratafias
- Add almond-like aroma and flavour; the second portion is sieved in for fresh flavour and texture.
The step that matters
Cooking the custard gently. Egg yolks set at a low temperature; if the mixture gets too hot it can curdle and turn grainy, so it should be cooked slowly and only until thickened.
Swap the lemon
How well each one fits the dish's main ingredients (cream, milk, sugar, egg):

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.
