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, whose firm flesh holds its shape through gentle stewing.
- Stock
- Forms the savoury liquid that cooks the eels and becomes the base of the gravy.
- Port or madeira
- Adds sweetness and depth of flavour to the stewing liquid and sauce.
- Cream
- Adds richness and body to the sauce once thickened with flour.
- Flour
- Thickens the cream and stock mixture into a smooth, coating sauce.
The step that matters
Boil the thickened mixture for 2 minutes. Flour must be fully boiled to swell its starch and thicken the sauce; without it the gravy stays thin and can taste raw and floury.
Swap the onion
How well each one fits the dish's main ingredients (clove, lemon, cream, flour, pepper):
- Arrowrootfits better
- Spinachfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against clove, lemon, cream, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
