Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main protein, which firms and flakes as it is gently simmered.
- Flour
- Dredges the eel and thickens the stock into a gravy.
- Stock
- Forms the liquid base that cooks the eel and becomes the gravy.
- Cream
- Adds richness and body to the gravy when stirred in.
- Port wine
- Adds depth and a little sweetness to the gravy.
The step that matters
Simmer the eel gently. Vigorous boiling toughens and breaks up delicate eel flesh, so keep the stock at a gentle simmer while the eel cooks.
Swap the mace
How well each one fits the dish's main ingredients (onion, lemon, clove, flour, pepper, cream, port wine):
- Nutmegfits better
- Marjoramfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against onion, lemon, clove, flour, pepper, cream, port wine. Candidates are from the same food group and used in at least 100 recipes.
