Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Small eels
- Break down during simmering to release gelatin and flavor into the broth.
- Water
- Serves as the cooking liquid that extracts flavor from the eels and aromatics.
- Onion
- Adds aromatic sweetness and savory depth to the broth.
The step that matters
Simmering the eels. Simmering gently rather than boiling keeps the broth clear and lets the eels release flavor and gelatin slowly without becoming cloudy or greasy.
