Winter Salad

Ingredients

Directions

Prepare the vegetables

  1. Peel the beetroot after cooking, taking care not to pierce the skin before cooking to retain its color.

  2. Wash, dry, and slice the celery.

  3. Wash and dry the watercress lightly.

  4. Separate the watercress into sprigs, cutting off the thick stalks.

  5. In a bowl, mix all the vegetables except the onion or parsley.

Make the sauce

  1. For the sauce, chop the yolk of the hard-boiled egg finely.

  2. In a bowl, rub the yolk, sugar, salt, pepper, and mustard together smoothly with a wooden spoon.

  3. Gradually stir in the olive oil, then the vinegar, and add the onion or parsley.

Assemble and serve

  1. Pour the sauce over the salad and sprinkle the chopped egg white on top.

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

What each ingredient does

Hard-boiled egg yolk
Its yolk, rubbed smooth with mustard and sugar, emulsifies the oil and vinegar into a thick, creamy dressing.
Olive oil
Provides fat and richness, carrying the flavour of the sauce and coating the vegetables.
Tarragon or plain vinegar
Adds acidity that sharpens the sauce and balances the sweetness and richness.
Prepared mustard
Acts as an additional emulsifier and adds sharp flavour that helps hold the sauce together.
Beetroot or carrot
Provides earthy sweetness, colour and body to the salad.
Potatoes
Add starch and bulk, giving the salad a substantial, soft texture.

The step that matters

Rubbing the yolk smooth with the seasonings. The yolk must be worked into a smooth paste before oil is added. Adding oil gradually lets the yolk's lecithin emulsify it into a stable sauce; lumps or rushing can cause the dressing to separate.

Swap the onion

How well each one fits the dish's main ingredients (beetroot, celery, potato, watercress, egg, olive, tarragon):
