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 ↓
Omelet
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the mixture
Add 2 tablespoons of water to the bread crumbs and season with pepper and salt.
Beat the eggs well and combine with the bread crumb mixture.
Cook and serve
Melt the butter in a flat pan and pour in the egg mixture.
Sprinkle the chopped parsley over the top.
Bake in a hot oven at 400°F (200°C) for about 15 minutes.
Serve with brown sauce, adding boiled asparagus ends cut into small pieces.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when heated to form the body of the omelet.
- Butter
- Adds richness and helps the omelet release from the pan.
- Bread crumbs
- Absorb moisture and give the omelet a lighter, softer texture.
The step that matters
Bake in a hot oven at 400°F (200°C) for about 15 minutes. Egg proteins set as they heat, so the omelet should be baked just until firm. Overbaking squeezes out moisture and makes it dry and rubbery.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter, bread, pepper):
- Parsleythe original
- Nutmegfits about as well
- Sagefits less well
- Tarragonfits less well
Fit is the average pairing score against egg, butter, bread, pepper. Candidates are from the same food group and used in at least 100 recipes.
