Halibut a LA Creme

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

Preheat the oven to 400°F (200°C).
Break the halibut into small pieces.
In a bowl, mix the milk, onion juice, butter, pepper, and salt.

Assemble and bake

In a baking dish, layer the fish and pour some sauce over each layer until the dish is full.
Sprinkle the top with bread crumbs.
Bake for 1 hour and 15 minutes.

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

What each ingredient does

Halibut: Forms the main body of the dish, cooking through into tender flakes.
Milk: Forms the sauce that moistens the fish as it bakes.
Butter: Adds richness and fat to the sauce, helping it taste rounded.
Bread crumbs: Form a crisp topping that browns in the oven.

Fit is the average pairing score against milk, butter, pepper, bread. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
