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 ↓
Tomato Sauce
Ingredients
Directions
Stew the tomatoes with the cloves, parsley, pepper, and salt for 30 minutes.
Press the mixture through a sieve.
In a saucepan, melt the butter over medium heat until bubbling. Add the flour and cook well, stirring constantly.

Optionally, add stock for improved flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body, acidity and flavor of the sauce.
- Butter
- Adds richness and fat, carrying flavor through the sauce.
- Flour
- Thickens the sauce as it cooks with the butter into a roux.
The step that matters
Cooking the flour in the butter. Flour must be cooked with the melted butter while stirring constantly; this cooks off raw starch taste and lets the flour thicken the sauce evenly without lumps.
Swap the tomato
How well each one fits the dish's main ingredients (clove, parsley, pepper, butter, flour):
- Shallotfits better
- Carrotfits better
- Parsnipfits better
- Tomatothe original
Fit is the average pairing score against clove, parsley, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
