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 ↓
Salad Dressing That Will Keep
Ingredients
Directions
Make the dressing base
Beat the eggs very lightly.
Gradually beat in the salad oil.
Add the strained lemon juice.
Season the cream
In a separate bowl, mix the cream with mustard, sugar, salt, black pepper, and red pepper until smooth.
Combine the cream mixture with the egg and oil mixture.
Add the vinegar and adjust to taste for sourness.
Thicken and cool
Set the bowl in a tin of hot water and stir continuously until it thickens.
Remove from heat and place the bowl in a dish of ice water, continuing to stir until smooth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg proteins thicken gently with heat and help emulsify the oil into the dressing.
- Salad oil
- Fat that forms the body of the dressing and gives it a smooth, rich mouthfeel.
- Cream
- Adds fat and body, softening the sharpness and giving a creamier texture.
- Mustard
- Its natural emulsifiers help hold the oil and liquids together and add sharp flavour.
- Vinegar
- Adds acidity that balances the richness of the eggs and oil.
The step that matters
Thickening over hot water. Egg proteins set when heated, so the bowl must be stirred constantly over gentle hot water. Overheating scrambles the eggs and leaves lumps, while stopping too early leaves the dressing thin.
