Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when cooked, binding the tomato mixture into a sliceable omelet.
- Tomatoes
- Provide moisture and acidity that give the omelet its main flavour.
- Onions
- Add sweetness and aroma as they soften during the simmer.
- Butter
- Adds richness and fat, carrying flavour through the tomato mixture.
- Cracker
- Crushed crumbs absorb liquid and thicken the tomato mixture.
The step that matters
Simmer the tomato mixture until thickened. Tomatoes hold a lot of water. A long, covered simmer lets the mixture soften and concentrate, so the eggs are not diluted and the omelet does not weep or stay wet when folded.
Swap the tomato
How well each one fits the dish's main ingredients (onion, butter, pepper, egg):
- Chivefits better
- Potatofits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against onion, butter, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
