Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Binds the mixture and adds richness, helping it set into a tender omelet.
- Mashed potatoes
- Adds body and moisture, giving the omelet a soft, tender texture.
- Milk
- Adds moisture, keeping the omelet soft rather than dry as it cooks.
- Cooked fish
- Provides the main flavor and protein, forming the body of the omelet.
- Drippings
- Fat for the pan that adds savory flavor and helps prevent sticking and browning.
The step that matters
Cooking the mixture until set. Cooking over medium heat until just set keeps the egg yolk tender; too much heat toughens the egg and dries the omelet.
Swap the potato
How well each one fits the dish's main ingredients (fish, butter, milk, egg, pepper):
- Potatothe original
- Capsicumfits about as well
- Asparagusfits less well
- Chivefits less well
Fit is the average pairing score against fish, butter, milk, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
