Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Planked Fish
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the plank
Preheat the oven to 400°F (200°C) and warm the plank for 5 minutes.
Butter the plank well and place the fish on it, skin side down.
Season and broil
Brush the fish with melted butter and lemon juice.
Broil the fish for about 15 minutes.
Remove the plank for a minute to decorate the fish with tomato slices, green peppers, pimientos, and onions.
Create a border of mashed potatoes around the fish using a pastry tube.
If using, place oysters or clams around the fish and top each with buttered bread crumbs.
Return the plank to the broiler and cook slowly for another 5 minutes until vegetables are done.
If using potatoes, brush them lightly with egg yolk to brown quickly.
Serve
Serve the fish on the plank on a large platter, garnished with lemon slices and parsley.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish and cooks through under the broiler.
- Melted butter
- Adds richness and moisture, helping the fish stay tender and brown lightly.
- Ripe tomatoes
- Contribute juice and acidity that moisten the fish and balance the richness of the butter.
- Mashed potatoes
- Form a starchy border that holds its shape and browns under the broiler.
- Egg yolk
- Promotes quick browning of the potato border when brushed on.
The step that matters
Return the plank to the broiler and cook slowly. Fish is delicate and dries out quickly under strong heat, so a brief, gentle finish keeps it moist while the vegetables soften and the potatoes brown.
