Why it works: Butter and walnut are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 6,832 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Planked Shad
Ingredients
Directions
Prepare the board
Prepare a thick oak board with wooden pegs.
Open and spread the shad, then lay it on the board and secure it with the pegs.
Cook
Place the board before a clear fire, resting one end in a shallow iron pan with a little salt and water.
Baste the fish with the saltwater as it cooks.
When almost cooked, baste with butter.
Serve
Serve with walnut catsup poured over the fish and garnish with pickled walnuts.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad
- Forms the main body of the dish, cooked whole on the board until flaky.
- Butter
- Adds fat and richness, and helps the fish brown lightly when basted near the end.
- Walnut catsup
- Adds a savoury, tangy flavour that complements the fish when poured over it at serving.
The step that matters
Basting with saltwater as the fish cooks. Basting keeps the surface moist while heat is applied from the fire, so the flesh does not dry out before it is cooked through. The salt in the pan adds seasoning as the liquid reduces and coats the fish.
Swap the walnut
How well each one fits the dish's main ingredients (spread, butter):
- Hazelnutfits about as well
- Almondfits about as well

- Peanutfits less well
Fit is the average pairing score against spread, butter. Candidates are from the same food group and used in at least 100 recipes.
