Why it works: Allspice and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 6,395 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Mackerel, Pickled
Ingredients
Directions
The book says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Clean and wash the mackerel, removing the roes.
Place the mackerel in an earthenware baking dish with the roes.
Sprinkle the fish well with coarse sea salt and black pepper.
Bake and serve
Add the bay leaves, allspice, peppercorns, vinegar, and water.
Cover with greased paper and bake in a cool oven at 300°F (150°C) for nearly 1 hour.
Let the mackerel remain in the liquid until ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Forms the main body of the dish and becomes firm and flaky as it bakes.
- Vinegar
- Acidity that sharpens the flavour and helps preserve the fish in the liquid.
- Coarse sea salt
- Seasons the fish and draws out moisture to firm its flesh.
- Bay leaves
- Adds a subtle aromatic, herbal flavour to the cooking liquid.
The step that matters
Baking in a cool oven under greased paper. A low, gentle heat cooks the fish through slowly so it stays tender rather than drying or breaking apart. The covering traps moisture so the fish steams in the vinegar and water rather than drying out at the surface.
Swap the allspice
How well each one fits the dish's main ingredients (vinegar, pepper):
- Tarragonfits better
- Dillfits better
- Parsleyfits about as well
- Allspicethe original
Fit is the average pairing score against vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
