Why it works: Fennel and pepper match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,216 recipes. Both carry myristicin, which smells spice, warm. The science ↓
To Boil Mackerel
Ingredients
Directions
Prepare
Clean the mackerel well and soak them in a mixture of vinegar and water for a short time.
Prepare fennel and butter, and green gooseberry sauce.
Cook
Boil water with coarse sea salt, then add the mackerel and cook for 15 minutes.
To souse the mackerel, mix ½ pint of vinegar with 1 quart of the boiling liquid, add black pepper, mace, and bay leaves.
Once cooled, cover the mackerel completely with the souse mixture, removing the bay leaves.
Serve
Serve garnished with fennel.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- The main fish, cooked gently in salted water to firm and flake.
- Vinegar
- Adds acidity that sharpens the flavour and helps preserve the souse.
- Black pepper
- Adds warm, pungent aroma to the souse.
- Bay leaves
- Infuse the souse with a herbal aroma.
- Green gooseberries
- Provide tartness in the sauce, balancing the richness of the butter.
Swap the mace
How well each one fits the dish's main ingredients (vinegar, fennel, butter, sauce, pepper):
- Tarragonfits better
- Parsleyfits better
- Dillfits better
- Macethe original
Fit is the average pairing score against vinegar, fennel, butter, sauce, pepper. Candidates are from the same food group and used in at least 100 recipes.
