Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Releases flavor and gelatin into the water, giving the broth body and savory depth.
- Egg whites
- Collect suspended particles as they cook, clarifying the broth into a clear liquid.
- Onion
- Adds aromatic sweetness and savory depth to the broth.
The step that matters
Boil quickly after adding the egg whites. Egg whites must be brought to a boil so they coagulate and trap cloudy particles. Boiling too gently or stirring too hard can leave the broth murky or break the raft apart.
