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 + white peppertop 20% of all pairs

    Shared aroma: isobutyraldehyde (malty, green).

    Shared aroma: 2-methylbutyraldehyde (malty, chocolate).

  3. Egg + vinegartop 33% of all pairs

    Shared aroma: acetic acid (sour, vinegar).

Egg and vinegar 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

Egg
Provides the protein that sets into the soft, tender poached white and yolk.
Vinegar
Acidity helps the egg white coagulate into a neater shape in simmering water.

The step that matters

Slip the egg into gently boiling water. Egg white begins to set on contact with heat, so a rolling boil or dropping the egg from height tears the white apart. Lowering it gently from a cup keeps the egg intact and the shape compact.

Swap the white pepper

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

  1. Tarragonfits better
  2. Dillfits better
  3. Parsleyfits better
  4. White pepperthe original

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