Salmon En Croquille

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.

Make the sauce

  1. Melt the butter in a saucepan.

  2. Add the flour, salt, and pepper, stirring to combine.

  3. Slowly add the milk and the liquor from the salmon, mixing well.

Assemble and bake

  1. Remove from heat and stir in the salmon, parsley, onion juice, lemon juice, and beaten egg yolks.

  2. Spoon the mixture into buttered shells and top with buttered crumbs.

  3. Bake at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Salmon
Provides the main body and flavor of the filling.
Egg yolks
Thicken the mixture when gently heated and bind it together as it sets.
Flour
Thickens the butter and milk into a smooth white sauce.
Milk
Forms the liquid base of the sauce that carries the filling.
Butter
Adds richness and carries flavor into the flour roux.
Lemon juice
Adds acidity that brightens the rich sauce and salmon.

The step that matters

Stir the egg yolks in off the heat. Egg yolks thicken and can scramble if they get too hot. Removing the pan from heat before adding them lets them bind the mixture smoothly without curdling.

Swap the white pepper

How well each one fits the dish's main ingredients (salmon, flour, butter, milk, parsley, onion, lemon):

  1. Capersfits better
  2. Thymefits better

  4. White pepperthe original

Fit is the average pairing score against salmon, flour, butter, milk, parsley, onion, lemon. Candidates are from the same food group and used in at least 100 recipes.
