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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Provides richness and a smooth, fluid body to the sauce.
- Egg yolks
- Thicken the sauce as they set gently with heat, adding richness.
The step that matters
Pouring the mixture between two basins. Egg yolks can curdle if they overheat and set in lumps. Pouring the warm mixture back and forth between basins cools it quickly and evenly, keeping the sauce smooth.
