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
Ingredients
Directions
In a bowl, whisk together eggs, milk, flour, parsley, green onions, shallot, pepper, salt, and nutmeg.
In a small frying pan, melt butter over medium heat.
Pour the egg mixture into the pan and cook until the bottom is golden brown.
Carefully flip the omelet to cook the other side until golden.
Fold the omelet in half and serve. Add ham or tongue if desired.

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 omelette as they cook, holding it together.
- Milk
- Adds moisture, keeping the eggs tender rather than dry and firm.
- Flour
- Thickens the egg mixture slightly, giving a more stable, less watery texture.
- Butter
- Coats the pan to prevent sticking and adds richness and golden browning.
The step that matters
Cook the bottom until golden, then flip carefully. Eggs set quickly over medium heat. Cooking gently until the base is golden gives a firm surface that can be flipped without tearing, while the inside stays tender.
Swap the shallot
The recipe marks shallot as optional. How well each one fits the dish's main ingredients (egg, milk, flour, parsley, onion, pepper, nutmeg):
- Chivefits about as well
- Shallotthe original
- Carrotfits about as well
- Spinachfits about as well
Fit is the average pairing score against egg, milk, flour, parsley, onion, pepper, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
