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, being careful not to pierce the skin before cooking.
Wash, dry, and slice the celery.
Wash and dry the watercress lightly, cutting off the thick stalks.
Mix all the vegetables (except the onion and parsley) in the center of a dish or bowl.
Chop the white of the hard-boiled egg finely.
Make the dressing
In a bowl, rub the yolk, sugar, salt, pepper, and mustard together smoothly.
Gradually stir in the olive oil and vinegar, then add the onion or parsley.
Assemble and serve
Pour the dressing 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
- Beetroot or carrot
- Adds colour, earthy sweetness and a firm, tender bite to the salad.
- Potatoes
- Provides body and bulk, soaking up some of the dressing to hold the salad together.
- Hard-boiled egg
- Yolk emulsifies into the dressing for a creamy texture; chopped white adds garnish and substance.
- Olive oil
- Carries flavour and gives the dressing a smooth, rich mouthfeel.
- Vinegar
- Adds acidity that sharpens the dressing and balances the oil and sweetness.
- Mustard
- Acts as an emulsifier, helping the oil and vinegar stay combined in the dressing.
The step that matters
Gradually stir in the olive oil and vinegar. Adding the oil slowly to the mustard and egg yolk lets the yolk emulsify it into a smooth dressing. Pouring it in all at once can cause it to separate and turn greasy.
Swap the onion
How well each one fits the dish's main ingredients (beetroot, celery, potato, watercress, egg, olive, tarragon):
