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 ↓

Salad Dressing

Ingredients

Directions

Make the dressing

  1. In a deep soup plate, place the yolks of four eggs, two teaspoons best ground mustard, three-quarters teaspoon of salt, half teaspoon cayenne pepper, and half teaspoon white pepper. With a large fork or spoon, stir continually in one direction.

  2. With the other hand, pour in the best olive oil slowly from time to time from the bottle. As soon as it commences to bind and get stringy, add quickly a little lemon juice or vinegar.

  3. Keep stirring continually until three-quarters of a pint of oil, the juice of one lemon, and one-half gill of vinegar are used up. Stir up well, then place at once on ice.

Fix a broken dressing

  1. If the dressing breaks, add quickly another yolk of egg and stir, holding back the oil for a minute.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Their emulsifiers hold the oil in tiny droplets, giving the dressing a smooth, thick body.
Oil
Forms the bulk of the dressing, suspended within the yolk mixture as fine droplets.
Mustard
Helps stabilise the emulsion so the dressing is less likely to separate.
Lemon juice
Adds acidity that brightens the flavour and helps the emulsion set.

The step that matters

Adding the oil slowly while stirring constantly. Egg yolk lecithin can only coat so many oil droplets at once. Pouring too fast or stopping to stir lets the oil separate out, so the dressing breaks.

Swap the white pepper

How well each one fits the dish's main ingredients (pepper, egg, mustard, lemon, vinegar):

  1. Tarragonfits better
  2. Dillfits better
  3. Parsleyfits better
  4. White pepperthe original

Fit is the average pairing score against pepper, egg, mustard, lemon, vinegar. Candidates are from the same food group and used in at least 100 recipes.
