Why it works: Pepper and tomato 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 ↓
Savoury Omelets
Ingredients
Directions
Prepare
Break the eggs into a bowl, add salt and pepper, and beat with a fork for a few minutes.
Cook the omelet
Heat an omelet pan and add the butter.
When the butter is steaming, pour in the eggs.
Make small incisions with a fork to allow heat to reach the eggs evenly.
Run a knife around the edge of the pan to prevent sticking.
Fold one half of the omelet over the other when it begins to firm up.
Serve
Shake the omelet onto a hot dish and pour the tomato sauce over it.

Butter and sauce barely smell alike, yet cooks put them together in 15,338 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into the soft, tender structure of the omelet as they cook.
- Butter
- Adds fat for richness and helps keep the eggs from sticking to the pan.
The step that matters
Make small incisions with a fork. Eggs set quickly on contact with a hot pan, so the centre can stay runny while the edges overcook. Small cuts let heat reach the middle and cook the eggs more evenly.
Swap the tomato
How well each one fits the dish's main ingredients (egg, pepper, butter, sauce):
- Capsicumfits better
- Asparagusfits better
- Shallotfits about as well
- Tomatothe original
Fit is the average pairing score against egg, pepper, butter, sauce. Candidates are from the same food group and used in at least 100 recipes.
