Brown Oyster Sauce

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.

Brown the base

  1. Brown the flour and butter in the oven at 400°F (200°C).

Finish the sauce

  1. Gradually add the stock or gravy until fully combined.

  2. Add the oysters and let simmer for a few minutes.

  3. Stir in the mushroom catsup and season with salt and pepper.

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

What each ingredient does

Flour
Thickens the sauce and, once browned, adds a nutty flavor.
Butter
Provides fat that carries flavor and helps the flour brown evenly.
Soup stock or gravy
Forms the liquid base that gives the sauce its body and savory flavor.
Oysters
Contribute a briny, savory flavor to the sauce.
Mushroom catsup
Adds concentrated savory depth and umami to the sauce.

The step that matters

Browning the flour and butter. Heat browns the flour and butter through Maillard reactions, creating nutty flavor and color. Too little time leaves a raw, pasty taste, while too much burns the mixture and makes the sauce bitter, so watch it closely.
