Why it works: Asparagus and pepper are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 1,968 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the butter and thicken the sauce as they gently cook.
- Butter
- Adds richness and fat that gives the sauce a smooth, silky body.
- Lemon juice
- Adds acidity that balances the richness and helps stabilise the emulsion.
The step that matters
Keep the water hot but not boiling. Egg yolks scramble when overheated, and the sauce turns grainy or curdled. Gentle, steady heat lets the yolks thicken slowly while butter emulsifies smoothly into them.
Swap the asparagus
How well each one fits the dish's main ingredients (butter, egg, vinegar, pepper):
