Salad Dressing

Ingredients

Directions

Make the dressing

  1. Cream the softened butter until light and fluffy.

  2. Stir in the egg yolks until smooth.

  3. Mix in the mustard and salt, then add cayenne or white pepper if desired.

  4. Slowly drizzle in the olive oil while stirring continuously.

  5. Combine the lemon juice and vinegar to make ½ cup, then add slowly to the mixture while stirring.

  6. Adjust the consistency by adding more vinegar if needed, tasting as you go.

Serve

  1. If using lettuce, add celery salt to the seasoning at the beginning.

  2. Do not pour the dressing over the salad until just before serving.

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

What each ingredient does

Butter
Adds richness and a smooth, creamy body to the dressing.
Egg yolks
Emulsifiers that bind the oil and vinegar into a stable, thick dressing.
Olive oil
Forms the bulk of the emulsion, giving the dressing its body and mouthfeel.
Prepared mustard
Acts as a further emulsifier and adds sharp, tangy flavour.
Vinegar
Adds acidity that brightens the flavour and balances the richness of the oil.
Lemon juice
Contributes acidity and fresh citrus aroma to the dressing.

The step that matters

Drizzling in the olive oil. Adding the oil slowly while stirring lets the egg yolks and mustard disperse it into tiny droplets. Adding it too fast can break the emulsion, leaving the dressing oily and separated.

Swap the white pepper

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

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