Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Deviled Salmon
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
Flake the salmon finely with a fork.
Crush the crackers into crumbs.
Assemble
In a well-buttered baking dish, layer the salmon and cracker crumbs alternately.
Season each layer with salt, pepper, paprika, onion, and butter.
Pour the hot water over the mixture.
Top with a final layer of cracker crumbs, dotted with butter.
Bake
Bake at 400 °F (200 °C) until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Provides the main body and savory flavor of the dish.
- Cracker crumbs
- Absorb liquid and help bind the layers into a soft, cohesive mass.
- Butter
- Adds richness and helps the top brown in the oven.
- Onion
- Adds savory aroma and sharpness that flavors the salmon layers.
- Hot water
- Moistens the crumbs and gently cooks the mixture as it bakes.
The step that matters
Baking until golden brown. Baking long enough lets the surface brown through Maillard reactions and the crumbs dry slightly, giving flavor and a firm top. Too little time leaves the center wet and pale, while too long can dry the salmon.

Fit is the average pairing score against salmon, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
