Why it works: Pepper and parsley 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 ↓
Spanish Omelette
Ingredients
Directions
Prepare the eggs
Beat the egg whites and yolks separately.
Add salt, pepper, flour, and milk to the yolks and mix well.
Pour the mixture into a buttered pan and cook until firm.
Make the sauce
In another pan, heat butter or olive oil and fry the bay leaf, onion, parsley, green pepper, mushrooms, ham, and lamb's kidney until cooked.
Add the tomatoes and consommé, and cook for 30 minutes.
Finish and serve
Pour the sauce over the omelette before folding it onto a plate.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whisked eggs set into the omelette's structure, giving it its body when cooked.
- Flour
- Thickens the egg mixture slightly, helping it hold together when cooked.
- Milk
- Adds moisture and softness to the eggs, keeping the omelette tender.
- Onion
- Softens and sweetens as it cooks, adding savoury depth to the filling and sauce.
- Tomatoes
- Break down into the sauce, adding moisture and gentle acidity.
The step that matters
Cook the egg mixture until firm. Cooking the egg mixture until it is just set, without overcooking, keeps the omelette tender and prevents it from becoming dry or rubbery before the sauce is added.
