Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat and bones
- Give the stock its body and rich meaty flavor as they simmer.
- Butter
- Softens the peppers and onions and carries their flavor into the soup.
- Flour
- Thickens the soup as the thin paste cooks into the liquid.
- Macaroni
- Adds starchy bulk and body, becoming tender as the soup simmers.
- Tomatoes
- Add acidity, body and a fresh tomato flavor to the soup.
The step that matters
Add the flour paste to the soup. Flour lumps if added as dry powder, so mixing it into a thin paste with cold water first lets it disperse evenly. Boiling afterward cooks out the raw starch taste and thickens the soup smoothly.
