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 ↓
Potato Omelet
Ingredients
Directions
Melt the butter in a skillet over medium heat.
Add the chopped potatoes, salt, pepper, and parsley; cook until browned.
In a bowl, beat the eggs and pour them into the skillet over the potatoes.
When the eggs begin to set, fold the omelet in half and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a structure that holds the potatoes together as the omelette cooks.
- Potatoes
- Provide the bulk and browned, starchy texture that fills the omelette.
- Butter
- Adds richness and helps the potatoes brown without sticking to the skillet.
The step that matters
Add the eggs when the potatoes are browned and let them set gently. Eggs cook quickly and turn rubbery if the heat is too high. Medium heat lets the proteins set slowly into a tender layer, and folding only once they begin to set keeps the omelette soft.
