Why it works: Clove and parsley match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and 6,768 recipes mention both. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Cream of Tomato Soup
Ingredients
Directions
Make the tomato base
Add 10 medium-sized tomatoes to 1 pt. of water, or 1 qt. of canned tomatoes, 1 teaspoon of sugar, 8 whole cloves, 1 onion, a little parsley, and boil fifteen or twenty minutes.
Add a small teaspoon of soda and, after a few minutes, strain.
Make the milk base
Thicken 1 qt. of milk with a large tablespoon of corn starch, stirring and boiling for ten minutes.
Combine and heat
Add a little salt, a sprinkling of cayenne, a heaping tablespoon of butter, and the tomato mixture, allowing the whole to become thoroughly heated through, but not to boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes (in the method)
- Provide the main body, acidity and flavor of the soup.
- Milk (in the method)
- Forms the creamy base that gives the soup its body and smooth texture.
- Corn starch
- Thickens the milk so the soup has a smooth, body-rich consistency.
- Butter
- Adds fat for a rich mouthfeel and smooth finish.
- Sugar
- Balances the acidity of the tomatoes with mild sweetness.
The step that matters
Heating the combined soup without boiling. Milk can curdle or separate when it boils, especially when acidic tomatoes are added. Heating gently keeps the soup smooth and creamy.

Fit is the average pairing score against sugar, butter, corn, clove, parsley. 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).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
