Why it works: Lemon and pepper 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 ↓
Escaloped Salmon
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the salmon
Remove all skin and bones from the salmon.
Break the salmon as little as possible.
Add lemon juice to the salmon.
Mix the salmon well.
Make the cream sauce
Combine milk, butter, flour, salt, and pepper in a saucepan.
Cook the mixture over medium heat until thickened.
Assemble and bake
Preheat the oven to 350°F (175°C).
Arrange half of the salmon in a buttered baking dish.
Sprinkle the salmon lightly with salt.
Pour half of the cream sauce over the salmon.
Layer the remaining salmon on top of the first layer.
Cover the salmon with the remaining cream sauce.
Mix melted butter into the bread crumbs.
Spread the buttered bread crumbs over the salmon mixture.
Bake in the preheated oven until browned.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Forms the bulk of the dish, giving it its main flavor and body.
- Milk
- Forms the base of the cream sauce, which moistens the salmon layers.
- Flour
- Thickens the milk and butter into a smooth sauce that holds the layers together.
- Butter
- Enriches the sauce and browns the bread crumb topping.
- Bread crumbs
- Form a crisp, golden topping when baked over the salmon.
The step that matters
Cook the cream sauce until thickened. Flour thickens only when the mixture is heated enough and stirred, so undercooked sauce stays thin and runs into the salmon, leaving the casserole watery.
Swap the lemon
How well each one fits the dish's main ingredients (salmon, milk, butter, flour, pepper, bread):
- Lemonthe original
- Figfits about as well
- Avocadofits about as well
- Coconutfits about as well
Fit is the average pairing score against salmon, milk, butter, flour, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
