Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Salmon Croquettes
Ingredients
Directions
Tear the cold salmon into shreds using two forks.
Chop a level teaspoon of onion and sauté it in butter over medium heat until it begins to turn yellow.
Stir in the flour and, when bubbling, gradually add the boiling milk, stirring until smooth.
Add the salmon, salt, white pepper, nutmeg, and egg yolks, mixing over heat for two minutes.
Spread the mixture an inch thick on an oiled dish and let it cool.
Shape the croquettes, fry them until golden brown, and garnish with fried parsley.
