Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef shank
- Releases flavor and body into the broth as it simmers.
- Ham shank
- Adds savory, salty depth to the broth during long simmering.
- Onions
- Contribute sweetness and aroma to the broth as they cook down.
- Ox liver
- Adds a rich, mineral-like depth and body to the broth.
The step that matters
Adding the ox liver and simmering until cooked. Liver cooks quickly and turns grainy and tough if overcooked. Keeping the heat gentle and watching for doneness helps it stay tender while the broth stays clear.
Swap the celery
How well each one fits the dish's main ingredients (beef, ham, onion, liver):
- Garlicfits better
