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 Bluefish
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the pan
Preheat the oven to 400°F (200°C).
Lay the larding pork slices in the bottom of a baking pan.
Sprinkle the chopped onion over the pork.
Place the bread slices on top of the onion.
Prepare the fish
Score the bluefish across the backbone in 4 or 5 places and insert pieces of larding pork into each gash.
Lay additional strips of pork over the surface of the fish.
Season the fish with salt and pepper, then dredge with flour.
Bake and serve
Cover the fish with another pan and bake until the flakes separate from the backbone.
Serve the fish in the baking pan with lemon quarters.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Larding pork
- Bastes the fish with fat as it bakes, keeping the flesh moist and adding savory flavor.
- Bluefish
- Forms the main body of the dish, cooking into flaky, moist flesh.
- Onion
- Softens and sweetens as it bakes, adding aromatic flavor to the pan juices.
- Bread
- Soaks up the rendered pork fat and onion juices, adding body to the pan base.
The step that matters
Covering and baking until the flakes separate. Covering traps steam so the fish cooks gently and stays moist. Pulling it too late dries the flesh, while the flakes separating from the backbone shows it is cooked through.
Swap the lemon

- Lemonthe original
- Limefits less well
- Cherryfits less well
Fit is the average pairing score against pork, onion, bread, bluefish, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
