Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gravy beef
- Provides the main meaty flavor and body as it simmers into the soup.
- Flour
- Browned flour thickens the soup and adds a deeper, nutty color.
- Butter
- Carries the browning of the meat, onion and flour and adds richness.
- Red currant jelly
- Adds sweetness and a fruity tang that balances the savory broth.
- Onion
- Adds savory sweetness and aroma as it browns in the butter.
The step that matters
Browning the flour. Flour browned in fat develops nutty flavor and color, but it can scorch quickly. Stir constantly over moderate heat and stop once it reaches a rich brown, since burnt flour turns bitter and cannot be fixed.
