Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main body of the soup and its flesh, which turns tender during simmering.
- Butter
- Adds richness and fat, helping the eels brown lightly and carrying flavour.
- Flour
- Thickens the cream mixture so the finished soup has body.
- Cream
- Adds richness and a smooth, velvety texture to the thickened broth.
The step that matters
Simmer until the eels are tender, being careful not to break them.. Eel flesh is delicate and falls apart if the heat is too high or it is stirred hard. Gentle simmering cooks it through while keeping the slices intact.
Swap the mace
How well each one fits the dish's main ingredients (onion, butter, flour, cream):
- Garlicfits better
- Capersfits better
- Nutmegfits better
- Macethe original
Fit is the average pairing score against onion, butter, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
