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
Thoroughly clean the fish and cut off the head if preferred.
Remove the backbone from the head to within 2 inches of the tail.
Soak the stale bread in water and squeeze dry.
Chop the onion and fry it in butter until soft.
Add the bread, 2 ounces of butter, salt, pepper, and parsley or sage; heat through.
Remove from heat and stir in the yolks of 2 beaten eggs.
Stuff the fish with the mixture, sew it up with twine, and wrap it with white tape.
Rub the fish with a little butter.
Cover the bottom of a baking pan with hot water and place the fish in it.
