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 ↓
Salmon Baked in Slices
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
Remove the bone from the salmon and cut the flesh into slices.
Season the slices with cayenne pepper and salt.
Make the sauce
Melt the butter in the water over low heat.
Mix in the port wine, ketchup, and anchovies.
Let the anchovies dissolve in the mixture, then strain it.
Bake and serve
Pour the sauce over the salmon slices.
Cover the dish with buttered paper and bake in a 350°F (175°C) oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon fillet
- Forms the main body of the dish, cooking into flaky, tender slices.
- Butter
- Enriches the sauce with fat, adding richness and a smooth, silky texture.
- Port wine
- Adds sweetness and depth of flavour to the sauce as it reduces and blends.
- Anchovies
- Dissolve into the sauce, adding savoury depth and umami without a clear fishy taste.
- Ketchup
- Contributes sweetness, acidity and tomato flavour to the sauce.
The step that matters
Let the anchovies dissolve in the mixture, then strain it.. Anchovies must fully break down in the warm liquid; undissolved pieces leave a gritty, salty texture. Straining removes what remains, giving a smooth sauce.
