Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Tomato Sauce
Ingredients
Directions
Make the sauce
Melt the butter in a saucepan over medium heat.
Add the onions, carrots, and ham; fry until browned.
Stir in the tomatoes, parsley, thyme, pepper, bay leaves, and salt.
Cover and cook slowly until the tomatoes are soft.
Thicken and strain
Thicken the sauce with flour diluted in cold broth to the desired consistency.
Stir well until it boils, then let it cook slowly for 30 minutes.
Remove the ham and parsley bundle, and strain the sauce through a fine sieve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and helps the vegetables brown in the pan.
- Ham
- Browns in the fat and adds savory, smoky flavor to the sauce.
- Tomatoes
- Form the body of the sauce and provide its acidity and fresh flavor.
- Flour
- Thickens the sauce as it is diluted and heated, giving it body.
The step that matters
Thicken with diluted flour. Flour added directly to hot liquid clumps. Mixing it into cold broth first lets the starch disperse evenly, so it thickens smoothly when the sauce boils.
