Salad Without Meats

Ingredients

Directions

  1. Separate and wash the lettuce leaves thoroughly.

  2. Soak the lettuce leaves in cold water to crisp.

  5. Add onion if desired.

Make the dressing

  1. Cook the yolk of one egg in a bowl, stirring constantly to make a smooth paste.

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 oil and lemon juice to give the dressing a smooth, creamy body.
Olive oil
Adds fat and richness, carrying flavour and giving the dressing a silky mouthfeel.
Lemon juice
Adds acidity that brightens the dressing and balances the richness of the yolks and oil.
Mustard
Acts as an emulsifier that helps hold the oil and yolk mixture together and adds sharpness.
Lettuce
Provides the crisp, watery base that the dressing coats and the other vegetables rest on.

The step that matters

Cooking the yolk into a smooth paste. Stirring the cooked yolk constantly keeps it from clumping or scrambling, so it blends evenly. Letting it cool before adding the raw yolks prevents the raw yolks from partly cooking on contact with heat, which keeps the dressing smooth.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (lettuce, tomato, cucumber, egg, mustard, sugar, olive):

  1. Endivefits better
  2. Chivefits better
  3. Broccolifits better
  4. Onionthe original

Fit is the average pairing score against lettuce, tomato, cucumber, egg, mustard, sugar, olive. Candidates are from the same food group and used in at least 100 recipes.
