Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beefsteak
- Long simmering releases flavor and gelatin into the broth, giving body to the soup.
- Browned flour
- Thickens the broth and adds a toasted, darker color and nutty flavor.
- Wine
- Adds acidity and aroma that brighten the rich, long-cooked broth.
- Potatoes
- Break down during cooking to add starch, body and mild sweetness to the soup.
The step that matters
Skim the surface constantly. Foam and fat rising during the long boil can cloud the broth and give it an greasy taste. Removing them keeps the soup clear and clean-flavored.
