Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Planked Whitefish
Ingredients
Directions
Prepare the fish
Clean, wipe, and split the whitefish, then trim it into shape.
Place the fish skin side down on a well-greased oak fish plank, which is 1½ inches thick and 2 inches longer and wider than the fish.
Brush the fish with melted butter.
Surround the fish with a border of coarse sea salt to prevent the plank from burning.
Cook and finish
Broil the fish for 20 minutes under the gas flame.
Remove from the oven and scrape off the salt border.
Spread the fish with melted butter and sprinkle with salt and pepper.
Pipe potatoes through a pastry bag to create a border around the fish.
Garnish with parsley and lemon slices.
Serve the fish on the plank placed on a large platter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whitefish
- Forms the main body of the dish, cooking through to flaky, tender flesh.
- Melted butter
- Adds fat and richness, keeping the surface moist and flavorful during broiling.
- Potatoes
- Piped as a border, they add a soft, starchy contrast to the fish.
The step that matters
Surround the fish with a coarse salt border. The salt border shields the exposed plank edges from direct heat so the wood does not scorch or burn under the broiler before the fish is cooked.
