Celery and Mushrooms À LA Crême

Ingredients

Directions

Prepare the vegetables

  1. Slice 1¼ quarts of celery into inch-thick slices and quarter or eighths 1 cup of mushrooms.

  2. Cook celery and mushrooms separately and drain.

  1. In a saucepan, heat ¼ cup oil and melted butter, add ¼–½ cup chopped onion, ¾ cup flour, 1 egg or yolk, 1 tsp chopped parsley, and salt.

  2. Simmer the onion mixture, add flour, then add boiling water to make a stiff sauce (about 1 pint); when smooth, remove from heat, add salt, parsley, and beaten egg.

  3. Use the liquid drained from celery and mushrooms with water in the sauce.

Bake and serve

  1. Layer the sauce, cooked celery, and mushrooms in a baking dish, topping with sauce.

  2. Sprinkle with crumbs or cornmeal, bake and brown in the oven.

  3. Optionally, add a little garlic, a small quantity of cream, and a small amount of strained tomato to the sauce.

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

What each ingredient does

Flour
Thickens the sauce so it holds its shape and coats the vegetables.
Egg
Binds the sauce and helps it set as it cooks.
Mushrooms
Add savory, earthy flavor and a tender texture to the layers.
Celery (in the method)
Provides the main bulk and a crisp-tender texture under the sauce.
Oil
Carries flavor and helps form the roux-like base of the sauce.

The step that matters

Cooking the flour into the sauce. Flour must be fully cooked and smoothed into the hot fat and liquid so the sauce thickens evenly without lumps or a raw starchy taste.

Swap the onion

How well each one fits the dish's main ingredients (mushroom, flour, egg, parsley):

  1. Shallotfits better
  2. Chivefits better
  3. Spinachfits better
  4. Onionthe original

Fit is the average pairing score against mushroom, flour, egg, parsley. Candidates are from the same food group and used in at least 100 recipes.
