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 ↓
Tortilla with Parsley
Ingredients
Directions
Make the tortillas
Beat the eggs well in a bowl.
Add the chopped parsley, chopped onion, salt, and pepper to the eggs.
Melt 1 ounce of butter in a sauté pan over medium heat.
Pour one‑third of the egg mixture into the pan to make the first tortilla.
Cook until set, then roll tightly and cut in half.
Repeat with the remaining egg mixture to make two more tortillas, using 1 ounce of butter for each.
Fry and serve
Cover each rolled tortilla with egg and bread crumbs.
Melt the remaining butter in the pan until boiling.
Fry the tortillas until golden brown.
Serve with plenty of fried parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Form the tortillas and set into a firm, sliceable structure when cooked.
- Butter
- Fats the pan and adds richness and golden browning when frying.
- Bread crumbs
- Coat the rolled tortillas, adding a crisp, golden outer layer when fried.
The step that matters
Cook until set, then roll tightly. Egg must be fully set before rolling; if it is still runny it tears and cannot hold a tight roll. Cooking over medium heat gives a set, flexible sheet without browning too quickly.
Swap the onion
How well each one fits the dish's main ingredients (egg, parsley, pepper, butter, bread):
- Shallotfits better
- Capsicumfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against egg, parsley, pepper, butter, bread. Candidates are from the same food group and used in at least 100 recipes.
