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
Prepare the fish
Cut off the fish head if preferred and remove the backbone, leaving 2 inches from the tail.
Make the stuffing
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 the fish with the mixture.
Bake and serve
Sew the fish up with fine twine.
Wrap the fish with white tape.
Rub the fish with butter.
Place it in a baking pan with a little hot water at the bottom.
Shape the fish into an S and bake until cooked through.
Mash the hard-boiled egg yolks into a smooth paste with salad oil.
Stir in mustard.
Add 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 of the dish, cooked gently in the baking pan.
- Stale bread
- Soaked and squeezed, it adds moisture and bulk to the stuffing.
- Butter
- Adds richness and moisture, and helps the fish brown lightly as it bakes.
- Egg yolks
- Bind the stuffing so it holds together when heated.
- Hard-boiled egg yolks
- Mashed with oil into a smooth, thick dressing that adds richness.
The step that matters
Shape the fish into an S and bake until cooked through. Fish cooks quickly and turns dry or flaky when overbaked, so check it for doneness rather than relying on a fixed time. Stuffing needs enough heat to set the egg yolks fully.
Swap the mustard
How well each one fits the dish's main ingredients (fish, onion, bread, butter, pepper, parsley, egg):
