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 the salmon
Remove the bone from the salmon and cut the flesh into slices.
Season the slices with cayenne pepper and coarse sea 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 liquid, then strain it.
Pour the sauce over the salmon slices.
Bake
Cover the dish with buttered paper and bake in a 350°F (175°C) oven until cooked through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Forms the main body of the dish, cooking through to a flaky texture.
- Butter
- Adds richness and fat, carrying flavour and giving the sauce a silky body.
- Port wine
- Adds sweetness and depth, and its acidity balances the rich butter.
- Anchovies
- Dissolve into the liquid to add savoury depth and salty umami.
- Ketchup
- Adds sweetness and tang, rounding out the sauce's flavour.
The step that matters
Let the anchovies dissolve in the liquid, then strain it. Anchovies must fully break down into the warm liquid so they add savoury depth without leaving pieces. Straining then gives the sauce a smooth texture before it is poured over the salmon.
