Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

White fish
Forms the main body of the dish, cooking gently on the plank as its flesh firms and turns opaque.
Butter or oil
Brushed on the fish to add moisture and help prevent it from drying out while baking.
Creamed butter
Spread over the cooked fish to add richness and a smooth, savory finish.
Lemon juice
Adds acidity that brightens the rich butter and balances the flavor of the fish.

The step that matters

Bake for about 25 minutes, basting often. Basting repeatedly with fat carries heat across the surface and keeps the fish moist. Without it, the thin areas of the fish can dry out before the thicker parts are fully cooked.

Swap the potato

How well each one fits the dish's main ingredients (fish, butter, lemon, pepper, parsley):

  1. Shallotfits about as well
  2. Carrotfits about as well
  3. Potatothe original
  4. Capsicumfits about as well

Fit is the average pairing score against fish, butter, lemon, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
