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
In a stewpan, combine the melted butter and egg yolks.
Place the stewpan in a saucepan of hot water over medium heat.
Stir continuously with a wooden spoon until the mixture thickens.
Season with salt and a few grains of Cayenne pepper.
Do not let the sauce boil, or it will curdle.
Just before finishing, stir in the lemon juice.

Egg and lemon barely smell alike, yet cooks put them together in 44,316 recipes: they work on texture and structure more than aroma.
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 set with heat.
- Melted butter
- Provides fat and richness, forming a smooth emulsion with the egg yolks.
- Lemon juice
- Adds acidity that brightens the rich butter and egg flavor.
The step that matters
Do not let the sauce boil. Egg yolks scramble and curdle when overheated. Gentle, indirect heat from the hot water bath lets them thicken smoothly into an emulsion.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
