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.

    Shared aroma: 3-hexenal (apple, fruity).

Lemon and egg barely smell alike, yet cooks put them together in 44,316 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
Egg yolk lecithin binds oil and water, letting the sauce emulsify and thicken.
Olive oil
Forms the bulk of the sauce, giving it body, richness and flavor.
Lemon juice
Adds acidity that brightens the flavor and balances the richness of the oil.

The step that matters

Adding the oil gradually. Oil must be dispersed as tiny droplets, each coated by egg yolk proteins and lecithin. Adding it in small amounts while beating lets the emulsion form. Adding too much at once can break the emulsion so the sauce stays oily and does not thicken.

Swap the lemon

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

  1. Lemonthe original
  2. Avocadofits about as well
  3. Pumpkinfits less well
  4. Cherryfits less well

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