The flavor team

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.

  1. Vinegar + mustardtop 7% of all pairs

    Cooked together14,067 recipes

    Shared aroma: isobutyraldehyde (malty, green).

  2. Egg + mustardtop 28% of all pairs

    Shared aroma: (e)-2-octenal (fatty, green).

  3. Vinegar + eggtop 33% of all pairs

    Shared aroma: acetic acid (sour, vinegar).

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
Egg yolks hold the oil and vinegar together as a stable emulsion, giving body and a creamy texture.
Oil
Makes up the bulk of the sauce and gives it its rich, smooth body and fat content.
Vinegar
Adds acidity that brightens the flavor and helps keep the emulsion stable.
Mustard
Contains natural emulsifiers that help the oil and yolk mix and stay combined.

The step that matters

Adding the oil while beating constantly. Oil must be broken into very fine droplets and dispersed through the yolk. Adding it too fast or stopping the beating lets the droplets merge, so the emulsion breaks and the sauce turns oily and runny.

Swap the mustard

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

  1. Cucumberfits about as well
  2. Mustardthe original
  3. Capsicumfits about as well
  4. Shallotfits less well

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