Why it works: Beetroot and watercress match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 143 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Winter Salad
Ingredients
Directions
Prepare the vegetables
Peel the beetroot after cooking, taking care not to pierce the skin before cooking to retain its color.
Wash, dry, and slice the celery.
Wash and dry the watercress lightly.
Separate the watercress into sprigs, cutting off the thick stalks.
In a bowl, mix all the vegetables except the onion or parsley.
Make the sauce
For the sauce, chop the yolk of the hard-boiled egg finely.
In a bowl, rub the yolk, sugar, salt, pepper, and mustard together smoothly with a wooden spoon.
Gradually stir in the olive oil, then the vinegar, and add the onion or parsley.
Assemble and serve
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):
