Why it works: Pepper and lemon 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 White 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 fish
Wash the fish well, scrape it, and split it down the whole length, removing the backbone carefully.
Tack the fish to a plank, inside up.
Season with pepper and coarse sea salt, and dot with bits of butter.
Bake and serve
Bake in a 400°F (200°C) oven for 20 to 30 minutes, avoiding overcooking.
Serve with lemon quarters.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the dish; its flesh cooks through in the oven and turns flaky when heated gently.
- Butter
- Adds richness and moisture as it melts over the fish during baking.
The step that matters
Avoiding overcooking. Fish proteins tighten as they heat, and past the point of doneness they squeeze out moisture, leaving the flesh dry and tough. Checking for early flaking within the 20 to 30 minute window keeps it moist.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
