Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg beaters egg whites
- Form the main body of the omelet and set into a tender, light structure when cooked.
- Cheese
- Melts when folded in, adding richness and binding the omelet together.
- Green bell peppers
- Add mild sweetness and moisture, softened by sauteing before the eggs go in.
- Red bell peppers
- Add mild sweetness and moisture, softened by sauteing before the eggs go in.
- Onions
- Contribute savory aroma and sweetness as they soften in the pan.
The step that matters
Pour egg whites over veggies. Egg whites set quickly over heat, so cooking too hot or too long makes them rubbery and dry. Cook gently until just partially set before folding, so the omelet stays tender.
Swap the onion
How well each one fits the dish's main ingredients (egg, pepper, cheese):
- Capsicumfits better
- Asparagusfits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against egg, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
