Mushroom Powder

Ingredients

Directions

Prepare the powder

  1. Prepare and dry the mushrooms carefully.

  2. Pound the dried mushrooms to a fine powder and sift it.

  3. If using spices, bake them in the oven briefly before mixing with the powder.

Store

  1. Immediately transfer the powder into small, dry bottles, cork, and seal them.

  2. Store the bottles in a very dry place to prevent moisture.

Make the sauce

  1. To make a sauce, combine 1 teaspoon of mushroom powder with ¼ cup of strong veal gravy, ¼ cup of cream, and 2 teaspoons of flour.

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

What each ingredient does

Mushrooms
Dried and powdered mushrooms supply concentrated savory, umami flavour to the powder and sauce.
Strong veal gravy
Provides the savory, meaty body that the sauce is built on.
Cream
Adds fat and richness, giving the sauce a smoother, rounder texture.
Flour
Thickens the sauce by absorbing liquid and gelatinising with heat.

The step that matters

Store the powder in a very dry place. Mushroom powder readily absorbs moisture, which can cause it to clump, lose flavour, and spoil. Sealing it in dry, airtight bottles keeps it stable.

Swap the mace

The recipe marks mace as optional. How well each one fits the dish's main ingredients (mushroom, veal, cream, flour):

  1. Nutmegfits better
  2. Turmericfits better
  3. Capersfits better
  4. Macethe original

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