Why it works: Fish and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,488 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Planked Shad
Ingredients
Directions
Prepare the plank
Prepare a thick oak board with wooden pegs.
Open and spread the fish, then lay it on the board and secure it with the pegs.
Cook
Place the plank before a clear fire, resting one end in a shallow iron pan with a little salt and water.
Baste the fish with the saltwater mixture while toasting.
When almost cooked, baste with butter.
Serve
Serve by adding walnut catsup to the gravy, pouring it over the fish, and garnishing with pickled walnuts.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad fish
- Is the main protein, cooked gently on the board so it stays moist and tender.
- Butter
- Adds fat and richness, and helps the fish brown and taste savoury at the end.
- Walnut catsup
- Adds a dark, tangy, savoury flavour to the gravy poured over the fish.
The step that matters
Basting with the saltwater mixture while toasting. The salted water keeps the surface of the fish moist as the heat dries it, and seasons the flesh. If the fish is left unbasted, the exposed surface can dry out before the centre cooks through.
Swap the walnut
How well each one fits the dish's main ingredients (fish, spread, butter):
- Walnutthe original
- Almondfits about as well
- Hazelnutfits less well
- Peasfits less well
Fit is the average pairing score against fish, spread, butter. Candidates are from the same food group and used in at least 100 recipes.
