Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hare
- Provides the main meat and rich, gamey flavour as it stews into the broth.
- Lean beef
- Adds more meat and body to the broth as it becomes tender during stewing.
- Ham or bacon
- Contributes salty, smoky flavour that seasons the broth as it cooks.
- Onions
- Add sweetness and aromatic depth to the broth as they soften in the stew.
- Soy sauce or harvey's sauce
- Adds savoury, umami depth to the finished soup after straining.
The step that matters
Straining the soup. Removing solids and fat clears the broth and keeps it from tasting greasy. Skimming off fat before reboiling gives a cleaner, more balanced flavour.
