Why it works: Egg and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Egg and vinegar barely smell alike, yet cooks put them together in 12,922 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
- Their lecithin emulsifies the butter into the sauce and gives it body as it thickens.
- Melted butter
- Supplies the fat that makes the sauce rich, smooth and silky.
- Vinegar
- Adds acidity and sharpness that balances the richness of the butter and yolks.
The step that matters
Gradually add the melted butter while whisking continuously. Egg yolks can only hold so much fat in emulsion. Adding the butter slowly while whisking lets the yolk lecithin bind each droplet. Adding it too fast can make the sauce split into greasy, separated layers.
