Why it works: Port wine and vinegar work together. They rank in the top 11% of all ingredient pairs, and cooks put them together in 598 recipes. Both carry 4-ethyl-2-methoxyphenol, which smells smoky, clove. The science ↓
Stewed Cod Fish, in Brown Sauce
Ingredients
Directions
Prepare the fish
Remove the skin from the fish and dust it well with flour.
Fry the fish quickly in a hot pan until golden brown, then drain on a sieve.
Stew the fish
Place the fish in a clean stewpan and pour in enough boiling brown gravy to nearly cover it.
Add the port wine or claret, chili vinegar or lemon juice, cayenne, and salt to taste.
Stew the fish gently until it just begins to break apart.
Finish and serve
Carefully lift the fish onto a hot serving dish.
In the gravy, stir in the softened butter kneaded with flour and a little pounded mace.
Bring the sauce to a boil for one minute, then pour it over the fish and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the flaky body of the dish, which softens and breaks apart as it stews.
- Flour
- Dusting helps the fish brown when fried and thickens the sauce with the butter.
- Butter
- Enriches the gravy, adding richness and a smooth, glossy texture when stirred in.
- Port wine or claret
- Adds depth and mild sweetness to the brown gravy.
- Brown gravy
- Forms the main sauce that coats and flavours the fish as it stews.
The step that matters
Stew the fish gently until it just begins to break apart. High heat or long cooking toughens and dries cod proteins and makes the flakes crumble into the sauce, so gentle heat and close timing keep the fish moist and intact.
Swap the mace
How well each one fits the dish's main ingredients (fish, flour, pepper, port wine, vinegar, butter, sauce):
- Tarragonfits better
- Capersfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against fish, flour, pepper, port wine, vinegar, butter, sauce. Candidates are from the same food group and used in at least 100 recipes.
