Why it works: Butter and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and 118,967 recipes mention both. Both carry decanal, which smells soap, orange peel. The science ↓
Hollandaise Sauce
Ingredients
Directions
Make the reduction
Put the bay leaves, peppercorns, and vinegar into a small pan over very gentle heat until the vinegar is well flavored and reduced to about 2 teaspoons.
Strain the mixture into a bowl or enamel pan.
Finish the sauce
Add the butter and egg yolks, then place the bowl in a pan of hot water.
Stir with a whisk or wooden spoon until the sauce thickens.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify with the butter and thicken the sauce as they gently cook.
- Butter
- Adds richness and fat that makes the sauce smooth and silky.
- Vinegar
- Adds acidity that gives the sauce a sharp, bright flavor.
The step that matters
Stirring over hot water until the sauce thickens. Egg yolks set at moderate heat and can scramble if overheated. Gentle, constant stirring over hot water, not direct heat, keeps the yolks smooth and lets the sauce thicken evenly.
