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 ↓
An Omelette
Ingredients
Directions
Prepare
Beat the eggs with cream, parsley, onion or chives, pepper, and salt.
Melt butter in a frying pan over medium heat.
Cook and serve
Pour the egg mixture into the pan and stir until a cake forms.
When browned, fold the omelette in half to cover the raw egg appearance.
Serve with gravy poured over the top.

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.
- Cream
- Adds moisture and softness, keeping the eggs tender rather than dry.
- Butter
- Adds fat for richness and helps the omelette brown in the pan.
The step that matters
Stirring until a cake forms. Eggs set quickly over heat. Stirring while they cook breaks them into soft curds, while leaving them still lets the base set into a sheet. Removing the pan from heat too late can make the eggs tough and dry.
Swap the onion
How well each one fits the dish's main ingredients (egg, cream, parsley, pepper, butter):
- Potatofits better
- Spinachfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against egg, cream, parsley, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
