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.

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

What each ingredient does

Eggs
Their proteins set as they cook, giving the dish its structure and body.
Butter
Adds richness and helps the undersides of the eggs brown.
Onion
Adds aroma and mild sweetness as it softens in the butter.

The step that matters

Turning the eggs. The underside must set and lightly brown before turning, so the white is firm enough to hold its shape. Turning too early can tear the white or break the yolk.

Swap the onion

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

  1. Capsicumfits better
  2. Asparagusfits better
  3. Chivefits better
  4. Onionthe original

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