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 ↓

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
- Emulsify with butter and set gently to form a thick, creamy structure.
- Butter
- Adds richness and fat, giving the whip a smooth, silky texture.
- Water
- Adds moisture that helps the yolks whip into a looser, frothy consistency.
- Chili vinegar
- Adds acidity and sharpness that balances the richness of the butter and yolks.
The step that matters
Whip over gentle heat. Egg yolks begin to set around 65 to 70°C. If the water bath is too hot or the mixture overheats, the yolks scramble and the sauce turns grainy instead of smooth and frothy. Keep the heat moderate and whip constantly.
