The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Hard-boiled egg yolks
Their rich, fatty body thickens the mash and gives the sauce its creamy texture.
Vinegar
Adds sharpness that cuts the richness of the yolks and loosens the mash into a smooth cream.
Grated horse-radish
Contributes the sharp, pungent heat and aroma that defines the sauce.

The step that matters

Add the vinegar gradually. Adding vinegar a little at a time while mashing lets the yolks blend into a smooth cream. Adding it all at once can leave lumps that are hard to work out.

Swap the radish

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

  1. Radishthe original
  2. Mustardfits about as well
  3. Cucumberfits less well
  4. Capsicumfits less well

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