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.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. In a bowl, mix salad oil, egg yolk, chopped onion, parsley, minced anchovy, salt, and cayenne.

  3. Spread the mixture over each slice of salmon.

Wrap and bake

  1. Grease parchment paper with butter and wrap each salmon slice in it.

  2. Place the wrapped salmon on a baking sheet and bake for 30 minutes.

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

What each ingredient does

Salmon
Forms the main body of each packet and cooks gently inside the parchment.
Egg yolk
Binds the seasoning mixture and adds richness to the topping.
Salad oil
Carries the seasonings and keeps the salmon moist as it cooks.
Onion
Adds aroma and mild sweetness as it softens in the packet.
Anchovy
Adds savory depth that blends into the salmon without tasting fishy.

The step that matters

Wrapping the parchment packets. The parchment must be sealed tightly so steam stays inside. This gently cooks the salmon in its own moisture and keeps the topping from drying out or leaking.
