Why it works: Pork and onion are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,214 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. 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 slices of larding pork 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
Slice the bluefish across the backbone in four or five places.
Insert a piece of larding pork into each gash of the fish.
Lay strips of pork over the surface of the fish.
Season the fish with salt and pepper, then dredge with flour.
Bake
Cover the fish with another pan and bake until the flakes separate from the backbone.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bluefish
- Forms the main body of the dish, and its flesh flakes apart when cooked through.
- Larding pork
- Adds fat that bastes the fish, keeping it moist and adding savory flavor as it renders.
- Onion
- Softens and sweetens as it cooks, adding aroma to the pan juices under the fish.
- Flour
- Dredged on the fish, it helps the surface brown and gives the juices some body.
The step that matters
Bake until the flakes separate, not longer. Fish proteins set and tighten as they heat, so overbaking squeezes out moisture and leaves the flesh dry and tough. Check for flakes separating from the backbone.
