Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Adds moisture, so the beaten egg cooks into a softer, more tender omelet.
- Butter
- Adds fat that keeps the egg from sticking and gives a rich, lightly browned flavor.
- Tomato
- Adds moisture and a fresh acidity that brightens the eggs.
- Onion juice
- Adds a sharp aroma that flavors the eggs without adding solid bits.
The step that matters
Hold the dish above the flame and scrape the bottom. Egg proteins set quickly when they touch hot metal. Moving the mixture over the heat and scraping the bottom keeps the curds soft and prevents the underside from scorching before the top sets.
Flavor stand-ins for the onion
How well each one fits the dish's main ingredients (milk, butter, pepper, tomato):

- Potatobetter flavor fit
- Carrotabout as good a flavor fit
- Onionthe original
Fit is the average pairing score against milk, butter, pepper, tomato. 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).
