Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Baked Salmon
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the fish
Preheat the oven to 350°F (175°C).
Spread chopped onion, parsley, and fine bread crumbs over the top of the fish.
Moisten the fish with water mixed with vinegar.
Bake until tender.
Make the sauce
In a saucepan, combine milk, flour, and butter.
Cook the mixture until thickened.
Stir in chopped hard-boiled egg and tomato ketchup.
Serve the sauce in a sauce boat alongside the salmon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whole salmon
- Forms the main body of the dish and is cooked through by baking.
- Bread crumbs
- Form a crust on the fish top and absorb moisture as they bake.
- Milk
- Forms the liquid base of the sauce, which thickens when heated with flour.
- Flour
- Thickens the milk and butter mixture into a smooth sauce.
- Butter
- Adds richness and fat to the sauce.
- Hard-boiled egg
- Adds body and a soft, rich texture to the sauce.
The step that matters
Cook the milk, flour and butter until thickened. Flour thickens liquid only when heated enough for its starch to swell. Stopping too early leaves a thin sauce, while overcooking can make it stick or scorch on the base of the pan.
Swap the parsley
How well each one fits the dish's main ingredients (salmon, onion, bread, vinegar, milk, flour, butter):
- Capersfits better
- Garlicfits better
- Parsleythe original
- Cinnamonfits about as well
Fit is the average pairing score against salmon, onion, bread, vinegar, milk, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
