Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Baked White 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
Cut out the backbone of the fish from the head to within 2 inches of the tail.
In a skillet, fry the chopped onion in 1 ounce of butter until soft.
Add the soaked bread, remaining butter, salt, pepper, and parsley or sage; heat through.
Remove from heat and stir in the beaten egg yolks.
Stuff and bake
Stuff the fish with the mixture, sew it up with twine, and wrap it with white tape.
Rub the fish with butter and place it in a baking pan with a little hot water at the bottom.
Bake at 350°F (175°C) until cooked through.
Make the dressing
For the dressing, mash the hard-boiled egg yolks with salad oil, mustard, pepper, and vinegar to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Forms the main body that is stuffed and baked until flaky and cooked through.
- Butter
- Adds richness and fat, helping the fish brown and stay moist while baking.
- Onion
- Softens into a sweet, savoury base that flavours the stuffing.
- Stale bread
- Soaked and squeezed, it absorbs moisture and gives the stuffing body.
- Egg yolks
- Beaten into the stuffing, they bind it as they set with gentle heat.
- Hard-boiled egg yolks
- Mashed into the dressing, they give it a smooth, rich, thick texture.
The step that matters
Bake until cooked through. Fish cooks quickly and turns dry when overcooked, while underdone fish is unsafe. The stuffing's raw egg yolks also need enough heat to set, so check that the thickest part is opaque and flakes easily.
