Why it works: Vinegar and port wine 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 ↓
To Bake Mackerel
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Place the cleaned mackerel in a deep dish.
Pour equal amounts of water and vinegar over the fish.
Add whole black pepper, a pinch of mace, coarse sea salt, bay leaves, and port wine.
Cover and bake
Cover the dish with a buttered sheet of thick white paper.
Alternatively, season the mackerel with finely powdered pepper, salt, and mace.
Place bits of butter in the bottom of the dish and on top of the mackerel.
Bake until cooked through.
Serve
Serve hot with parsley and melted butter, or cold with vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- The main fish, which becomes flaky and tender as its proteins set during baking.
- Vinegar
- Adds acidity that gives the fish a sharp, tangy flavour.
- Butter
- Adds richness and moisture as it melts over the fish.
- Port wine
- Adds sweetness and depth of flavour to the fish.
- Bay leaves
- Add a subtle herbal aroma to the cooking liquid.
- Black pepper
- Adds a sharp, warm aroma and gentle heat.
The step that matters
Bake until cooked through. Mackerel turns dry and tough once overcooked, as its proteins tighten past the point of doneness. Checking the fish early and keeping the buttered paper over the dish traps steam, which helps it stay moist.
Swap the mace
How well each one fits the dish's main ingredients (vinegar, pepper, port wine, butter):
- Tarragonfits better
- Parsleyfits better
- Clovefits better
- Macethe original
Fit is the average pairing score against vinegar, pepper, port wine, butter. Candidates are from the same food group and used in at least 100 recipes.
