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
Wash and dry the shad pieces.
Mix the allspice, black pepper, and coarse sea salt, then sprinkle the seasoning over each piece of shad.
Cure and cook
Place the seasoned shad in a stone jar and cover with cider vinegar.
Cover the jar with a clean cloth and tie several layers of brown paper over it.
Set the jar in a 350°F (175°C) oven and let it cook for 12 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad
- The main protein; slow cooking in vinegar softens its bones and flesh until it can be potted.
- Cider vinegar
- Acidity that helps soften the fish and preserves it while it cooks in the jar.
- Ground allspice
- Adds warm, aromatic flavour that carries through the long cooking.
The step that matters
Sealing the jar for the long bake. The cloth and paper layers keep the jar covered so the fish stays submerged in vinegar and cooks gently over 12 hours rather than drying out or spoiling at the surface.
Swap the allspice
How well each one fits the dish's main ingredients (pepper, cider, vinegar, fish):
- Tarragonfits about as well
- Allspicethe original
- Thymefits about as well
- Clovefits about as well
Fit is the average pairing score against pepper, cider, vinegar, fish. Candidates are from the same food group and used in at least 100 recipes.
