Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Baked Fish
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 stuffing
Make a dressing by mixing bread crumbs, chopped onion, melted butter, beaten egg, black pepper, and coarse sea salt.
Stuff the fish with the dressing and tie it securely.
Bake
Preheat the oven to 350°F (175°C).
Place the stuffed fish in a pan with a little hot water.
Lay pieces of salt pork on top of the fish and season with thyme.
Bake the fish, basting very often until cooked through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, cooked through by baking in the pan.
- Salt pork
- Lays fat over the fish as it bakes, adding richness and moisture to the surface.
- Bread crumbs
- Absorb the beaten egg and butter to form a binding stuffing that holds its shape.
- Beaten egg
- Binds the stuffing together so it holds its shape during baking.
- Butter
- Adds fat and richness to the stuffing, contributing moisture and flavor.
The step that matters
Bake the fish, basting very often until cooked through.. Frequent basting keeps the surface moist as heat cooks the fish, helping prevent it from drying out before the center is done.
Swap the onion
