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 ↓
Potted Shad
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cut the shad into pieces, wash, and dry them.
Mix the allspice, black pepper, and coarse sea salt, then sprinkle over each piece of shad.
Pot and bake
Place the shad in a jar and cover with enough cider vinegar to submerge them.
Seal the jar tightly and bake in a moderate oven at 350°F (175°C) for twelve hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad
- The main fish, whose flesh softens and turns tender during the long, slow bake.
- Ground allspice
- Adds warm, aromatic spice notes that carry through the fish during the long cook.
- Black pepper
- Adds sharp, pungent heat that balances the richness of the fish.
- Cider vinegar
- Its acidity sharpens the flavor and helps keep the fish preserved in the jar.
- Coarse sea salt
- Seasons the fish and draws out moisture, helping it firm up and preserve.
The step that matters
Submerge the shad fully in vinegar before sealing. Pieces left above the liquid are not protected by the vinegar's acidity and may cook or keep unevenly. Fully covering them helps the fish stay evenly seasoned and preserved through the long bake.
Swap the allspice
How well each one fits the dish's main ingredients (pepper, cider, vinegar):
- Allspicethe original

- Clovefits about as well
- Thymefits about as well
Fit is the average pairing score against pepper, cider, vinegar. Candidates are from the same food group and used in at least 100 recipes.
