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 fish
Cut off the fish head if preferred.
Remove the backbone, leaving 2 inches from the tail.
Make the stuffing
In a pan, fry the chopped onion in 1 ounce of butter until soft.
Add the soaked bread, remaining butter, salt, pepper, and parsley or sage.
Heat the mixture through.
Remove from heat.
Stir in the beaten egg yolks.
Stuff and bake
Stuff the fish with the mixture.
Sew the fish up with twine.
Wrap the fish with white tape.
Rub the fish with the remaining butter.
Place the fish in a baking pan with a little hot water.
Shape the fish into an S.
Bake at 350°F (175°C) until cooked through.
Make the sauce
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
- Provides the main body that is stuffed and baked until cooked through.
- Butter
- Adds richness and moisture, and helps the fish brown in the oven.
- Onion
- Softened in butter, it adds sweetness and aroma to the stuffing.
- Stale bread
- Soaked and squeezed, it binds the stuffing and keeps it moist.
- Egg yolks
- Beaten yolks bind the stuffing so it holds together when heated.
- Hard-boiled egg yolks
- Mashed into the sauce, they give it a thick, smooth, creamy body.
The step that matters
Bake at 350°F (175°C) until cooked through. Fish cooks quickly and becomes dry and tough if overbaked, while underbaking leaves it unsafe. The stuffing also needs enough heat to set the beaten yolks, so check the thickest part of the fish.
