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 and finish
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 begins to break apart.
Carefully lift the fish onto a hot serving dish.
In the gravy, stir in the softened butter kneaded with flour and a pinch of 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 fish
- Provides the flaky body that softens and breaks apart during gentle stewing.
- Flour
- Dusting helps the fish brown in the pan and lightly coats the surface.
- Brown gravy
- Forms the savoury sauce base that the fish is stewed in.
- Port wine or claret
- Adds depth and a fruity sweetness to the sauce as it simmers.
- Butter
- Kneaded with flour, it enriches the sauce and thickens it with a silky body.
The step that matters
Stewing the fish gently. High heat or vigorous boiling can make the delicate fish fall apart too early and toughen its proteins. A gentle simmer lets it soften while staying in pieces.
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.
