Salad Dressings, to Make Cold

Ingredients

Directions

Make the dressing

  1. In a bowl, mix the mustard and salt with enough vinegar to form a paste using a fork.

  2. Add the egg yolk and stir thoroughly.

  3. Gradually add the sweet oil or melted butter, one teaspoon at a time, while mixing.

  4. If the dressing becomes too thick, add a teaspoon of vinegar as needed.

  5. Continue adding oil or butter and vinegar until you reach the desired consistency.

  6. Taste and adjust seasoning with more salt or mustard if necessary.

Serve

  1. Serve the dressing over chopped cold vegetables or meats and mix well.

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

What each ingredient does

Egg yolk
Emulsifies the oil and vinegar so the dressing stays smooth and thick.
Ground mustard
Helps stabilise the emulsion and adds sharp flavour.
Sweet oil or melted butter
Provides fat that gives the dressing body and richness.
Vinegar
Adds acidity that brightens the dressing and thins it as needed.

The step that matters

Adding the oil or butter. Adding fat too quickly breaks the emulsion, so the dressing separates and looks greasy. Adding it slowly, a teaspoon at a time while mixing, lets the egg yolk bind the oil into a smooth, stable dressing.

Swap the mustard

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

  1. Cucumberfits about as well
  2. Shallotfits about as well
  3. Mustardthe original
  4. Chivefits about as well

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