Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbit
- Provides the meat that becomes tender during long simmering, giving the soup its body and flavor.
- Flour
- Coats the rabbit so it browns in the frying fat and helps thicken the soup.
- Onions
- Frying them to a clear brown builds a deep, sweet savory base for the broth.
- Carrots
- Release natural sugars during long simmering, adding gentle sweetness and body to the broth.
The step that matters
Boil gently for 5 to 5.5 hours until the rabbit is soft. A gentle simmer lets connective tissue break down slowly, making the meat tender. A hard boil toughens the meat and clouds the broth, so keep it at a slow bubble.
