Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the soup and gives it a substantial, starchy body.
- Onions
- Add sweetness and savory depth as they soften during the long simmer.
- Tomatoes
- Contribute acidity and moisture, helping build the soup's flavor base.
- Beef soup stock
- Provides the main liquid and the beefy savory flavor of the soup.
- Flour
- Thickens the soup's liquid, giving it body as it boils.
The step that matters
Thicken the soup with flour as for beef soup.. Flour must be stirred in evenly and the soup kept boiling so the starch swells and thickens without leaving lumps or a raw floury taste.
Swap the tomato
How well each one fits the dish's main ingredients (onion, beef, flour):
- Chivefits better
- Leekfits better
