Why it works: Sugar and cream 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Provides the liquid base and dairy richness for the custard.
- Sugar
- Adds sweetness and helps soften the frozen texture.
- Egg whites
- Set and thicken when heated, giving the custard its body.
- Arrowroot
- Thickens the mixture when boiled, giving a smooth custard-like consistency.
- Whipped cream
- Adds fat and air, making the finished ice cream light and creamy.
The step that matters
Boil the mixture until it thickens. Egg whites and arrowroot need to reach a boil to thicken the base fully. Stopping early leaves a thin custard that may stay runny after cooling and freezing.
Swap the arrowroot
How well each one fits the dish's main ingredients (milk, sugar, egg, cream):
- Potatofits better
- Sweet potatofits better
- Asparagusfits better
- Arrowrootthe original
Fit is the average pairing score against milk, sugar, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
