Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbits
- Provide the meat and bones that give the soup its body and savory flavor.
- Ham or salt pork
- Adds salty, smoky fat that flavors the broth during the long stew.
- Onions
- Add sweetness and aromatic depth as they soften in the broth.
- Browned flour
- Thickens the broth slightly and adds a toasted, nutty flavor.
- Catsup
- Adds tomato sweetness and acidity to round out the broth.
- Worcestershire sauce
- Adds tangy, savory depth that boosts the overall umami of the soup.
The step that matters
Slow stew of the rabbit bones. Simmering gently for the full 3 hours lets collagen and marrow from the bones dissolve into the broth, giving body and flavor. A hard boil can make the broth cloudy and the meat tough.
