Why it works: Capers and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 405 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓

Tartar Sauce

Ingredients

Directions

  1. In a basin, rub the yolk of a cold hard boiled egg through a sieve.

  2. Add the raw egg yolks, salt, and pepper; mix with a wooden spoon.

  3. Gradually add the salad oil while stirring continuously until the mixture thickens.

  4. Moisten with a little tarragon or common vinegar, then continue adding oil until all is used, keeping the sauce thick.

  5. Stir in the gherkins, capers, shallot, parsley, French mustard, cayenne pepper, and more salt if needed.

  6. The sauce is now ready for use.

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

What each ingredient does

Raw egg yolks
Emulsify the oil into the sauce and thicken it as it is whisked.
Salad oil
Forms the body of the sauce, giving it richness and a thick, spoonable texture.
French mustard
Helps hold the emulsion together and adds sharp flavour.
Gherkins
Add acidity and crunch that cut through the richness of the oil.
Capers
Add salty, sharp flavour that brightens the sauce.

The step that matters

Gradually add the salad oil while stirring continuously. Oil must be added slowly while stirring so the yolks can emulsify it. Adding it too fast can break the emulsion, leaving a thin, oily sauce that will not thicken.

Flavor stand-ins for the cucumber

How well each one fits the dish's main ingredients (egg, pepper, capers, shallot, parsley, mustard, tarragon):

  1. Chivebetter flavor fit
  2. Horseradishbetter flavor fit
  3. Lettucebetter flavor fit
  4. Cucumberthe original

Fit is the average pairing score against egg, pepper, capers, shallot, parsley, mustard, tarragon. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
