Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eel
- Provides the main protein and rich flavor that the stewing liquid carries.
- Flour
- Coats the eel and thickens the strained liquid into a light sauce.
- Onion
- Adds aromatic sweetness and body to the stewing liquid as it simmers.
- Fish stock or water
- Forms the cooking liquid that gently simmers the eel and carries the spices.
The step that matters
Thickening the strained liquid. Flour must be blended smoothly before it goes into the hot liquid; otherwise it clumps instead of thickening evenly. Stirring while it heats lets the starch swell and form a uniform sauce.
Swap the mace
How well each one fits the dish's main ingredients (onion, pepper, clove, lemon, fish, flour):
- Thymefits better
- Cardamomfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against onion, pepper, clove, lemon, fish, flour. Candidates are from the same food group and used in at least 100 recipes.
