Why it works: Beef and mushroom are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,232 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Soles or Eels Stewed
Ingredients
Directions
Fry and simmer
Half-fry the soles or eels until slightly browned, then drain excess fat.
Season with pepper and coarse sea salt, and cover with beef gravy.
Simmer gently for 15 to 20 minutes, depending on thickness, without overcooking.
Carefully lift the fish with a slice.
Finish the sauce
Thicken the sauce with flour and butter, then flavor with mushroom ketchup and port wine.
Simmer for 1 to 2 minutes, then strain the sauce over the fish.
For a variation, mix the thickening with 1 cup of good cream, seasoned with cayenne and nutmeg, and optionally add a spoonful of ketchup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soles or eels
- Form the main body of the dish, staying firm when gently simmered.
- Flour
- Thickens the sauce so it coats the fish rather than running thin.
- Butter
- Enriches the thickened sauce and adds richness and smooth body.
- Beef gravy
- Forms the savory liquid that the fish simmers in and the sauce is built on.
- Port wine
- Adds sweetness and depth of flavor to the sauce.
- Mushroom ketchup
- Adds concentrated savory, umami flavor to the sauce.
The step that matters
Simmer gently without overcooking. Fish proteins toughen and flake apart when held at a hard boil or cooked too long, so a gentle simmer keeps the soles or eels tender and intact.
