Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Potato Omelet
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the potatoes
Peel and wash the potatoes, then bake them in their jackets.
Scoop out the insides and pass them through a sieve.
Make the mixture
Beat the egg whites and yolks separately.
Mix the beaten eggs with the potatoes, adding salt and pepper to taste.
Butter a pie dish and pour the mixture in.
Bake and serve
Bake in a 350°F (175°C) oven for 15 to 20 minutes.
Serve immediately, as it gets heavier when cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy bulk that gives the omelet its soft, light body.
- Eggs
- Set during baking to bind the potatoes and give structure and richness.
The step that matters
Beat the egg whites and yolks separately. Beaten whites trap air, which helps the omelet rise and stay light. Folding them into the potato mixture gently keeps that air from being lost.
Swap the potato
How well each one fits the dish's main ingredients (parsley, egg, milk, pepper):
- Capsicumfits about as well
- Carrotfits about as well
- Potatothe original
- Spinachfits about as well
Fit is the average pairing score against parsley, egg, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
