Ingredients
Directions
Make the dressing
Rub the yolks of the hard-boiled eggs through a fine sieve into a bowl.
Add the anchovy paste and French mustard, then mix well with a wooden spoon.
Slowly dilute the mixture with oil and vinegar.
Assemble and serve
In a separate bowl, combine the sliced beet, celeriac, potatoes, and pickles.
Season with coarse sea salt and pepper, then add the dressing along with tarragon and rampion.
Mix everything together and transfer to a salad bowl.
Garnish with small pieces of the hard-boiled egg whites and yolks, capers, and stuffed olives.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Yolks are pressed into the dressing, giving it body and a rich, creamy texture.
- Anchovy paste
- Adds a deep, salty savoury note that rounds out the dressing.
- French mustard
- Adds sharpness and helps emulsify the oil and vinegar into the dressing.
- Oil
- Provides fat that carries flavour and gives the dressing a smooth, glossy body.
- Vinegar
- Adds acidity that brightens the dressing and balances the rich yolks and oil.
- Potatoes
- Provide starchy body so the salad holds substance alongside the vegetables.
The step that matters
Slowly dilute the mixture with oil and vinegar. Adding oil gradually to the yolk and mustard mixture lets it emulsify into a smooth, stable dressing; adding it all at once can cause it to split and turn greasy.
Swap the potato

- Shallotfits better
- Lettucefits better
