Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomato Omelet
Ingredients
Directions
Make the tomato base
Remove the skin from the tomatoes and chop them finely.
In a saucepan, combine the tomatoes, chopped onions, butter, salt, pepper, and crushed cracker. Cover and simmer for about 1 hour.
Cook the omelet
Beat the eggs until frothy.
Heat a griddle and grease it well.
Stir the beaten eggs into the tomato mixture and pour onto the griddle. Brown on one side, then fold and brown on the other side.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and moisture that flavour the omelet.
- Eggs
- Set when cooked, binding the tomato mixture into a firm omelet.
- Onions
- Add sweetness and aroma as they soften during simmering.
- Butter
- Adds richness and fat for flavour and browning on the griddle.
- Cracker
- Absorbs liquid from the tomatoes, helping the mixture hold together.
The step that matters
Simmering the tomato mixture. Simmering evaporates excess liquid from the tomatoes, so the mixture is thick enough to set with the eggs instead of making the omelet watery.
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.
