Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Neck of beef
Breaks down slowly during simmering to give the broth body and meaty flavor.
Cornstarch
Thickens the soup as it is stirred in, giving it a smoother, heavier body.
Stewed tomatoes
Add acidity and tomato flavor that brightens the broth.
Macaroni
Adds starchy pasta pieces that soften in the hot soup and make it more filling.

The step that matters

Stir the cornstarch in while the soup is hot. Cornstarch thickens only when heated, and it clumps if dropped in as dry powder. Mixing it with cold water first and stirring it into simmering liquid lets the starch disperse and swell evenly, giving a smooth, thickened soup.

Swap the clove

How well each one fits the dish's main ingredients (beef, tomato, onion, parsley, pepper):

  1. Thymefits better
  2. Garlicfits better
  3. Celeryfits better
  4. Clovethe original

Fit is the average pairing score against beef, tomato, onion, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
