Why it works: Onion and biscuit work together. They rank in the top 8% of all ingredient pairs, and cooks put them together in 428 recipes. Both carry coumarin, which smells sweet, hay. 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
Preheat the oven to 350°F (175°C).
In a baking dish, layer the salmon, onions, rolled biscuits, and butter alternately until all ingredients are used.
Season with pepper and coarse sea salt.
Bake
Bake in the oven until heated through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Provides the main protein and flaky texture of the dish.
- Onions
- Add sweetness and aroma as they soften during baking.
- Soda biscuits
- Soak up juices and add body, helping bind the layers together.
- Butter
- Adds fat and richness, keeping the layers moist as they heat.
The step that matters
Bake until heated through. The salmon is already cooked, so the goal is only to warm it. Baking too long dries out the fish and toughens its texture, so check it as it heats rather than baking for a long time.
Swap the onion
How well each one fits the dish's main ingredients (salmon, biscuit, butter, pepper):
