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 ↓
Plain Omelet
Ingredients
Directions
Prepare the eggs
Beat the eggs very light and strain them through a sieve.
Add pepper and salt to taste.
Mix in the small pieces of fresh butter.
Cook and serve
Heat ¼ pound of butter in a frying pan over medium heat until boiling.
Pour in the beaten egg and fry gently until the underside is light brown.
Do not turn the omelet while cooking.
To brown the top, hold a hot shovel over it.
When done, fold the omelet in half and place it on a dish.
Garnish with sprigs of curled parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a delicate structure that forms the body of the omelet.
- Butter
- Adds richness and flavor, and helps keep the omelet from sticking to the pan.
The step that matters
Do not turn the omelet while cooking. Eggs set from the bottom up. Turning or stirring breaks the forming curds and can tear the delicate layer, so the omelet stays tender and intact when browned underneath and folded.
