Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Baked Omelette, with Herbs
Ingredients
Directions
Prepare the base
Beat the yolks of the eggs until light.
Stir in the milk and arrowroot until smooth.
In a pudding or pie dish, melt the butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trapped in foam and set proteins give the omelette its light, risen structure.
- Milk
- Adds moisture and softness, so the custard-like interior stays tender rather than dry.
- Butter
- Melted fat in the hot dish helps the base brown and release cleanly, adding richness.
- Arrowroot
- Starch that thickens the yolk mixture slightly, helping it hold its shape when baked.
The step that matters
Mix the yolks and whites together quickly. Folded egg white foam loses air if it sits or is overworked, and the omelette will not rise well. Combine promptly and then get the mixture into the hot oven.
Swap the arrowroot
How well each one fits the dish's main ingredients (egg, milk, butter, parsley, celery, onion, pepper):
- Carrotfits better

- Chivefits better
- Arrowrootthe original
Fit is the average pairing score against egg, milk, butter, parsley, celery, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
