Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Baked Haddock
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Fill the cleaned haddock with forcemeat and sew it up.
Sprinkle the fish generously with coarse sea salt and bread crumbs.
Dot the fish with pieces of butter.
Bake and serve
Bake for 45 minutes, basting frequently.
To make the sauce, combine milk and water in a pan, add a pinch of salt, and thicken with flour.
Garnish the platter with sliced lemon and parsley before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Forms the main body of the dish, cooking into flaky, tender meat.
- Bread crumbs
- Add a crisp, browned crust on the outside of the fish and absorb some moisture.
- Butter
- Adds richness and moisture, and helps the surface brown during baking.
- Egg
- Binds the forcemeat so it holds together inside the fish.
- Flour
- Thickens the milk and water into a smooth sauce.
The step that matters
Basting frequently during the 45-minute bake. Regular basting moistens the surface of the fish as it cooks, reducing drying and helping the crumbs and butter brown evenly. Lean fish can dry out quickly in dry oven heat.

Fit is the average pairing score against haddock, bread, butter, beef, pepper, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
