Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
To Bake 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the dish
Preheat the oven to 350°F (175°C).
Place the salmon slices in a dish.
Make the sauce
Melt the butter in a saucepan.
Stir the melted butter into the flour.
Add the gravy, port wine, catsup, anchovies, and cayenne.
Cook the sauce until the anchovies dissolve.
Strain the sauce.
Assemble and bake
Pour the sauce over the salmon.
Cover the dish with buttered paper.
Bake in the oven for 20-25 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- The main ingredient, baked under the sauce so it stays moist and tender.
- Butter
- Melted with the flour to form a roux that starts the sauce's thickening.
- Flour
- Thickens the sauce with the melted butter as it cooks.
- Gravy
- Forms the main liquid base of the sauce and carries its savory flavor.
- Port wine
- Adds sweetness and depth of flavor to the sauce.
- Anchovies
- Dissolve into the sauce, adding a salty, savory depth without a fishy taste.
The step that matters
Cook the sauce until the anchovies dissolve. Simmering fully dissolves the anchovies and cooks the flour, so the sauce thickens smoothly and does not taste raw or pasty.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
