Why it works: Fish and bread are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 1,668 recipes. Both carry 2-undecenal, which smells sweet. The science ↓
Baked Fish and Onion Dressing
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).
Rub the fish with coarse sea salt.
In a bowl, mix the dry bread, pepper, chopped onions, and salt.
Stuff and bake
Stuff the fish with the dressing and sew it up.
Place a few slices of bacon on top of the fish.
Bake for 2 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whole fish
- Forms the main body of the dish and cooks gently inside the oven heat.
- Dry bread
- Absorbs moisture and holds the dressing together while it cooks.
- Onions
- Add sweetness and aroma as they soften and mellow in the oven.
- Bacon
- Adds fat that bastes the fish and browns the surface as it bakes.
The step that matters
Stuffing the fish. Packing the dressing loosely leaves room for heat to reach the centre, so the dressing and fish cook through evenly. Packing it tightly can leave the middle undercooked while the outside overcooks.
Swap the onion
How well each one fits the dish's main ingredients (fish, pepper, bread):
- Capsicumfits better
- Tomatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against fish, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
