Why it works: Lemon and pepper 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 ↓

Ingredients
Directions
Prepare the seasoning
In a bowl, mix and sift the sugar, salt, mustard, and both peppers.
Slowly add the cream while stirring constantly until smooth, then set aside.
Make the dressing
Beat the egg yolks until light, then gradually add the melted butter while beating continuously.
Slowly add the lemon juice, then the cream mixture, and finally the vinegar, beating well after each addition.
Place the mixture in a double boiler and stir until it thickens.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the butter and thicken the dressing as they set with gentle heat.
- Melted butter
- Adds richness and a smooth, silky mouthfeel to the emulsion.
- Cream
- Adds body and softness, cushioning the dressing's sharp acidity.
- White vinegar
- Adds sharp acidity that brightens the dressing and balances the richness.
- Lemon juice
- Adds fresh acidity and aroma that lifts the rich, creamy base.
- Sugar
- Adds sweetness that rounds out the sharpness of the vinegar and lemon.
The step that matters
Heating in the double boiler. Egg yolks thicken as their proteins set, but if the heat is too high or unmoving they can scramble and turn grainy. Gentle, constant stirring over simmering water keeps the dressing smooth while it thickens.
Swap the mustard
