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
Combine cream, sugar, egg yolks, and vanilla extract in a saucepan.
Heat the mixture over low heat, stirring until it begins to thicken.
Strain the mixture through a fine sieve into a bowl.
Freeze
Place the bowl in a freezer.
When nearly frozen, fold in the crushed macaroons and an additional tablespoon of vanilla extract.
Continue freezing until fully set.

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 and add richness and structure as they set when heated.
- Cream
- Provides fat for a smooth, rich texture in the frozen ice cream.
- Sugar
- Sweetens the base and keeps the frozen ice cream softer by lowering its freezing point.
- Crisp macaroons
- Add crunchy texture and a toasted, almond-like sweetness to the frozen custard.
The step that matters
Heat the mixture over low heat, stirring until it begins to thicken.. Egg yolks scramble if overheated, leaving lumps. Gentle heat and constant stirring thicken the custard smoothly before freezing.
