Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Dutch Sauce
Ingredients
Directions
Melt the butter and place it in a saucepan.
Add the egg yolks to the melted butter.
Set the saucepan in a larger pan of hot water over medium heat and stir with a wooden spoon.
Season with salt and a light sprinkle of Cayenne pepper.
Stir continuously until the sauce thickens, ensuring it does not boil to prevent curdling.
Just before finishing, stir in the lemon juice.

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 into a smooth, rich sauce as they gently heat.
- Melted butter
- Provides fat that carries flavor and gives the sauce its silky, rich body.
- Lemon juice
- Adds acidity that brightens the rich butter and egg flavor.
The step that matters
Keep the heat gentle while stirring. Egg yolks thicken when heated gently, but boiling or strong heat scrambles them and causes curdling. Stirring constantly over indirect hot water spreads the heat evenly and keeps the sauce smooth.
