Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 34,122 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Ramekins of Eggs with Tomato Sauce
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the sauce
Melt the butter in a pan.
Add the onion, parsley, and green pepper; cook until slightly browned.
Stir in the flour and cook until frothy.
Add the cooked tomatoes and stir until boiling, then strain the mixture.
Bake and serve
Place 1-2 tablespoons of sauce in each ramekin and break an egg over the sauce.
Bake in a 400°F (200°C) oven for about 6 minutes, or until the egg is set.
Top with hot tomato sauce 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 when baked, forming the soft, cooked centre of each portion.
- Butter
- Carries the aromatics and provides fat for flavour and a smooth base.
- Flour
- Cooked with the butter to form a roux that thickens the tomato sauce.
- Cooked tomatoes
- Form the main body and acidic, savoury flavour of the sauce.
- Onion
- Softened and browned in the butter to add sweetness and depth to the sauce.
The step that matters
Bake until the egg is just set. Egg proteins set with heat, so a few minutes too long makes the yolk firm and chalky. Checking the white for opacity while the yolk still moves keeps the texture soft.

Fit is the average pairing score against butter, parsley, pepper, flour, tomato, sauce, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
