Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus tips
- Serve as the main vegetable, with tender texture when kept hot.
- Egg yolks
- Emulsify with butter and set when heated, thickening the sauce into a smooth custard.
- Lemon juice or vinegar
- Adds acidity that balances the richness of the butter and sharpens the flavor.
- Butter
- Adds fat that enriches the sauce and gives it a smooth, creamy body.
The step that matters
Stir over low heat until thickened. Egg yolks begin to set around 65°C (150°F). Too much heat scrambles them into curds, so gentle, constant stirring keeps the sauce smooth.
Swap the lettuce
How well each one fits the dish's main ingredients (asparagus, egg, lemon, butter):
