Why it works: Parsley and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Omelet. No. 5
Ingredients
Directions
Prepare
Break the eggs into an earthen pan.
Add pepper, salt, and enough water to dissolve the salt; beat the eggs well.
Melt the butter in a frying pan over medium heat.
Cook and serve
Pour the eggs into the pan and keep turning them continually, ensuring the middle does not cook over the fire.
Gather the edges and roll the omelet before it is fully cooked, keeping the middle hollow.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into the structure of the omelet as they cook, giving it body and a tender texture.
- Butter
- Adds fat and flavor and keeps the eggs from sticking to the frying pan.
The step that matters
Keep the middle from cooking while turning the eggs. Egg proteins set quickly with heat. Constant turning spreads the heat and keeps the centre soft, so the omelet stays tender and can be rolled without becoming dry or rubbery.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (egg, pepper, butter, onion, shallot):
- Capersfits about as well
- Parsleythe original
- Tarragonfits about as well
- Thymefits less well
Fit is the average pairing score against egg, pepper, butter, onion, shallot. Candidates are from the same food group and used in at least 100 recipes.
