Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main protein and flavor in the broth as it simmers.
- Macaroni
- Adds body and starch to the soup as it cooks until tender.
- Flour
- Thickens the broth slightly as it cooks in the soup.
- Tomato ketchup
- Adds acidity and sweetness that give the broth a tangy depth.
The step that matters
Stirring in the flour. Flour added directly to hot liquid can clump into lumps. Mixing it well so it disperses evenly lets it thicken the broth smoothly.
Swap the tomato
How well each one fits the dish's main ingredients (beef, onion, pepper, ketchup, flour):
- Turnipfits better
- Capsicumfits better
