Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a smooth, creamy body to the sauce.
- Egg yolks
- Emulsify with the butter to thicken the sauce into a smooth, rich texture.
- Hard-boiled eggs
- Chopped whites add body and a mild, firm texture to the sauce.
- Mutton
- Provides the main meat, warmed through in the sauce.
- Sherry
- Adds acidity and aroma that cut through the rich butter.
The step that matters
Keep the sauce warm without overheating. Butter and egg yolks can split or curdle if they get too hot, leaving the sauce grainy instead of smooth. Cooking gently while stirring keeps the emulsion stable.
