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 Shad
Ingredients
Directions
Soak stale bread in water and squeeze dry.
Cut the onion into pieces and fry in butter.
Chop finely and add the bread, 2 ounces of butter, salt, pepper, and parsley or sage; heat thoroughly.
Remove from heat and stir in 2 yolks of well-beaten eggs.
Stuff the mixture into the fish and wind it several times with tape.
Place in a baking pan, baste slightly with butter, and cover the bottom of the pan with water.
For the sauce, reduce the yolks of 2 hard-boiled eggs to a smooth paste.
Add 2 tablespoons olive oil, ½ teaspoon mustard, and pepper and vinegar to taste.
