Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Provide the main body and starch that give the soup its substance.
- Fat beef
- Adds savory, meaty flavor and fat to the broth as it simmers.
- Butter
- Carries the flour in the white sauce and adds richness.
- Flour
- Thickens the white sauce and, if added, the soup itself.
- Milk
- Forms the liquid base of the white sauce, adding creaminess and body.
The step that matters
Whisking the milk into the roux. Adding the milk gradually while whisking keeps the butter and flour mixture smooth; dumping it in at once can leave lumps that are hard to remove.
