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 ↓
A Small Savoury Omelet
Ingredients
Directions
Prepare
Break the eggs into a bowl and add the parsley, pepper, and salt.
Beat the eggs lightly.
Melt the butter in a small omelet pan over high heat.
Cook and serve
Pour the eggs into the pan.
Shake and stir the mixture vigorously until it begins to set.
When some of the egg is set and the rest is still liquid, tilt the pan and draw the egg to one side.
Leave it to set for a few seconds, then tilt the pan again and fold the omelet to the other side.
Once the outside is set, turn it onto a hot dish and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set by heat to form the omelet's structure and soft, tender texture.
- Butter
- Coats the pan so the omelet releases cleanly and adds richness.
The step that matters
Shake and stir the mixture vigorously until it begins to set. Constant agitation breaks up the egg into small curds so it cooks evenly and stays tender. If it sits still, the bottom overcooks and toughens before the top sets.
