Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Tomato Omelet
Ingredients
Directions
Prepare
Soak the bread pieces in the canned tomatoes for several minutes.
Cook the omelet
Heat half of the fat in a hinged omelet pan until bubbling hot.
Beat the eggs and pour an equal amount into each side of the pan.
Add the soaked bread and tomatoes, and season with salt and pepper.
Reduce the heat and use a silver knife to prevent sticking, tilting the pan to allow liquid to flow underneath.
When still soft, fold one half of the omelet over the other and slide it onto a hot platter.
Garnish with parsley and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into the structure of the omelet as they cook, holding the filling together.
- Bread pieces
- Soak up tomato liquid and add body, keeping the filling soft and moist.
- Canned tomatoes
- Add moisture and acidity, flavoring the eggs and softening the bread.
- Fat
- Greases the hot pan so the omelet releases cleanly and browns lightly.
The step that matters
Reduce the heat and tilt the pan. High heat toughens and browns egg proteins too fast, so the omelet can scorch or stick before it sets. Lowering the heat lets the eggs set gently while tilting lets uncooked egg flow underneath.
Swap the tomato
How well each one fits the dish's main ingredients (egg, bread, butter, pepper, parsley):
- Shallotfits better
- Capsicumfits better
- Chivefits better
- Tomatothe original
Fit is the average pairing score against egg, bread, butter, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
