Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes: Provide starchy bulk and a soft, tender body to the omelette.
Pepper jack cheese: Adds fat, melting richness and savoury flavour that binds the mixture.
Eggs: Set when baked to hold the mixture together and give it structure.
Unsalted butter: Adds fat for richness and helps keep the bake moist and tender.
Jalapeno: Contributes heat and fresh, grassy pepper flavour.
Horseradish: Adds a sharp, pungent bite that cuts through the richness.

The step that matters

Baking the egg mixture. Eggs set as their proteins coagulate with heat. Baking too long or too hot can make the omelette dry and rubbery, so watch for a set centre rather than relying only on the time.

Fit is the average pairing score against potato, pepper, cheese, egg, butter, mustard, horseradish. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
