Why it works: Pepper and fennel 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 ↓
Collared Salmon
Ingredients
Directions
Prepare
Select a piece of salmon sufficient to make a handsome roll, then wash and dry it.
Mix coarse sea salt, white pepper, ground mace, and Jamaica pepper to season the fish generously.
Rub the seasoning inside and out of the fish, then roll it tightly and bandage it.
Poach and pickle
In a pot, combine enough water and ⅓ cup vinegar to cover the fish, adding bay leaves, salt, both types of pepper, and a bunch of fennel.
Remove the fish and drain it; boil the liquid for an additional 10 minutes, then strain it.
Once cooled, pour the liquid over the fish.
Serve
Before serving, remove the tapes and garnish with fennel.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- The main ingredient, rolled tightly so it holds a neat, even shape when sliced.
- Vinegar
- Adds acidity to the cooking liquid, sharpening the flavour and firming the surface of the fish.
- Black pepper
- Adds sharp, aromatic heat that seasons the fish and the cooking liquid.
The step that matters
Once cooled, pour the liquid over the fish.. The liquid must be fully cooled before it touches the fish. Hot liquid would keep cooking the flesh, making it dry and breaking its texture, while cool liquid lets the fish absorb flavour gently.
Swap the white pepper
How well each one fits the dish's main ingredients (salmon, mace, pepper, vinegar, fennel):
- Tarragonfits better
- Dillfits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against salmon, mace, pepper, vinegar, fennel. Candidates are from the same food group and used in at least 100 recipes.
