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 1.5 inches thick and 2 inches longer and wider than the fish.
Brush the fish with melted butter and surround it with a border of coarse sea salt to prevent the plank from burning.
Cook and serve
Broil the fish under the gas flame for 20 minutes.
Remove from the oven and scrape off the salt border.
Spread the fish with more melted butter and sprinkle with salt and pepper.
Garnish with potatoes forced through a pastry bag, 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, moist flesh under the heat.
- Melted butter
- Adds moisture and richness, helping the fish stay tender and browning the surface.
- Coarse sea salt
- Forms a protective border that shields the plank edges from scorching during cooking.
The step that matters
Surrounding the fish with the salt border. The salt border keeps the exposed plank from burning under the broiler flame. Salt is packed around the fish, so it should be scraped off after cooking, before serving.
