Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Supply the main flesh of the soup, which becomes tender as it stews slowly.
- Onion
- Softens and sweetens during stewing, adding savory depth to the broth.
- Mace
- Adds a warm, aromatic spice note to the broth.
The step that matters
Stew gently until the flesh is fully cooked. Keeping the liquid at a gentle simmer cooks the eel through while helping the pieces hold together. A hard boil can toughen the flesh and break it apart, and stopping too early leaves the flesh undercooked.
Swap the mace
How well each one fits the dish's main ingredients (onion, parsley, bread, butter):
- Thymefits better
- Garlicfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against onion, parsley, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
