Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Cream Tomato Soup
Ingredients
Directions
Make the broth
Combine the beef, cold water, and salt in a pot; bring to a boil, skimming often.
Reduce heat and simmer for 2 hours.
Add the tomatoes and stew for 1.5 hours.
Pass the mixture through a sieve back into the pot and boil for 10 minutes.
Thicken and finish
In a small bowl, mix the butter and flour, then thicken the soup with this mixture.
Add a dash of cayenne pepper.
Stir in the hot sweet cream before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Simmers into the broth, giving it a savory, meaty body.
- Ripe tomatoes
- Provide the main body, acidity, and tomato flavor once stewed and sieved.
- Butter and flour
- Form a roux-style mixture that thickens the soup.
- Sweet cream
- Adds richness and mellows the acidity of the tomatoes.
The step that matters
Thicken with the butter and flour mixture. Flour clumps if added raw to hot liquid. Mixing it with butter first coats the grains so they disperse smoothly and thicken the soup evenly.
Swap the tomato
How well each one fits the dish's main ingredients (beef, butter, flour, pepper, cream):
- Potatofits better
- Leekfits better
- Chivefits better
- Tomatothe original
Fit is the average pairing score against beef, butter, flour, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
