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
Prepare the fish
If desired, first fry the fish until slightly browned, then drain excess fat.
Season the fish with pepper and coarse sea salt.
Stew and finish the sauce
Cover the fish with beef gravy and let it simmer gently for 20 minutes, adjusting time based on thickness.
Carefully remove the fish with a slotted spoon.
Thicken the sauce with flour and butter, then flavor with mushroom ketchup and port wine.
Simmer the sauce for 1-2 minutes, then strain it over the fish.
Alternatively, mix the thickening with 1 cup of cream seasoned with cayenne and nutmeg, with or without 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
- The main fish, which turns tender and flaky during gentle simmering in the gravy.
- Beef gravy
- Forms the cooking liquid that gives the sauce its savory, meaty base.
- Flour
- Thickens the sauce as it cooks with butter, giving it body.
- Butter
- Enriches the sauce and combines with flour to form the thickening roux.
- Port wine
- Adds sweetness and depth of flavor to the finished sauce.
- Cream
- Adds richness and a smooth, velvety texture to the alternative sauce.
The step that matters
Simmer gently. Gentle simmering keeps the fish tender and intact, while a hard boil can break it apart and toughen the flesh. Thickness affects how long it needs, so check it as it cooks.
