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 ↓
Baked 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 400°F (200°C).
Clean and scale the fish, then place it in a baking dish.
Season the fish with salt and pepper.
Slice the lemon and place the slices inside the fish.
Dot the fish with butter and sprinkle with fresh herbs if using.
Bake
Bake for 20-25 minutes or until the fish flakes easily with a fork.
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
- Whole fish
- Forms the main body of the dish, cooking gently in the oven until flaky.
- Butter
- Adds richness and moisture, helping the fish stay tender as it bakes.
- Lemon
- Adds acidity and aroma that brighten the mild flavour of the fish.
The step that matters
Bake until the fish flakes easily. Fish cooks quickly and turns dry and tough when overcooked. Checking that it flakes easily with a fork shows the flesh is just cooked through and still 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.
