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 ↓

Ingredients
Directions
Make the pepper base
Heat oil in a large skillet over low heat.
Add sliced green bell peppers and sliced onions; cover and cook, stirring occasionally, for 10 minutes, or until the onions are tender but not browned.
Add chopped whole tomatoes, ½ teaspoon salt, and ¼ teaspoon pepper; cook over medium heat about 3 minutes.
Increase the heat to high and cook about 1 minute, or until most of the liquid evaporates.
Remove to a serving dish and keep warm.
Scramble the eggs
Melt butter in the skillet.
Combine eggs, milk, 1 teaspoon salt, and ½ teaspoon pepper in a bowl; stir well.
Add mixture to the skillet and cook, stirring, until thickened.
Transfer to the serving dish with the green bell pepper mixture.
Sprinkle with parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken into soft curds, forming the body of the scramble.
- Green bell peppers
- Provide the main vegetable bulk and sweet, grassy flavor of the dish.
- Onions
- Soften and turn sweet as they cook, adding depth to the pepper base.
- Canned tomatoes
- Add acidity and moisture that cook down into the flavorful base.
- Butter
- Adds richness and fat that carries flavor and softens the eggs.
The step that matters
Cooking the egg mixture until thickened. Eggs set quickly and turn rubbery or dry if overcooked, so stirring over moderate heat until just thickened keeps them soft and creamy.
