Why it works: Onion and cumin are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,498 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Mexican Omelet
Ingredients
Directions
Make the filling
Cook beef and onion in a large skillet over medium‑high heat until meat is browned and onion is tender; drain.
Add chili powder and next 4 ingredients and simmer over medium‑low heat 5 to 7 minutes or until vegetables are slightly tender.
Make the omelettes
Whisk together Egg Beaters and pepper.
Melt margarine in skillet coated with cooking spray, rotating pan to coat bottom evenly.
Add half of egg mixture.
As egg mixture starts to cook, gently lift edges of omelet with a spatula and tilt pan so uncooked portion flows underneath.
Flip omelet over.
Sprinkle one side of omelet with half of meat mixture and one‑third cup cheese.
Slide omelet onto plate, folding over filling.
Keep warm and repeat process with remaining omelet.
Serve
Serve with salsa, sour cream and green onions, if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean ground beef
- Provides the main protein and savory body of the filling.
- Egg whites
- Set into the structure of the omelette when cooked, giving it a tender, light body.
- Cheddar cheese
- Melts into the filling, adding richness and a creamy texture.
- Bell peppers
- Add sweetness and crisp-tender texture to the meat filling.
- Onion
- Adds sweetness and aroma as it softens in the skillet.
The step that matters
Lifting the edges while the egg sets. Tilting the pan and lifting the cooking edges lets uncooked egg flow underneath, so the omelette cooks evenly into a thin, tender sheet instead of a dense, rubbery layer.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (beef, cumin, pepper, egg, cheddar cheese, milk, cream):
- Capsicumfits better
- Potatofits better
- Spinachfits about as well
- Onionthe original
Fit is the average pairing score against beef, cumin, pepper, egg, cheddar cheese, milk, cream. Candidates are from the same food group and used in at least 100 recipes.
