Ingredients

Directions

Make the sauce

  1. In a saucepan, combine the sliced onion, horseradish, anchovies, alder vinegar, and stock.

  2. Bring to a boil and simmer for about 10 minutes.

  3. Strain the mixture through a fine sieve back into the saucepan.

Thicken and finish

  1. In a bowl, whisk the eggs to create a liaison.

  2. Stir the liaison into the sauce and heat on the stove until it begins to boil.

  3. Remove from heat and continue stirring until cooled.

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.

Vinegar and egg barely smell alike, yet cooks put them together in 12,922 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Eggs
Thicken the sauce as a liaison, setting gently when heated.
Anchovies
Add savory depth, giving the sauce a salty, umami backbone.
Alder vinegar
Adds acidity that sharpens the sauce and balances its richness.
Horseradish
Provides the sharp, pungent aroma and heat characteristic of the sauce.

The step that matters

Adding the liaison to the hot sauce. Egg proteins set when heated, so if the sauce boils after the eggs go in, they can curdle and turn grainy. Stirring constantly and heating gently keeps the sauce smooth and thickened.

Swap the onion

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

  1. Mustardfits better
  2. Cucumberfits better
  3. Shallotfits better
  4. Onionthe original

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