Mushroom powder in soup and broth
Simmering mushrooms into a liquid is the oldest preparation there is, and a fine powder is the shortcut version: all of the material with no straining afterward. A pot of soup will absorb a serving without anyone calling it a mushroom soup.

The species that belong in a pot
Maitake is the cooking species on our shelf. It brings genuine savory depth to stock, pan sauces, gravies, and anything built on onions and butter. A tablespoon whisked into a pot of soup deepens it the way a spoonful of good stock concentrate would.
Reishi has been simmered into liquid for centuries, and broth is one of the two places its woody bitterness sits naturally. In a long-simmered bone broth or a miso-style soup, a half serving adds a dark, tea-like edge that suits the dish. Johnny Blend Plus splits the difference and disappears into almost any base.
When to add it, and how much
Whisk the powder into a ladle of hot broth to make a smooth slurry, then stir the slurry back into the pot near the end of cooking. Adding it to the ladle first keeps the pot lump-free, and adding it late keeps the flavor bright rather than boiled down.
A level tablespoon per two to four servings of soup is a comfortable starting point. For a single mug of broth, a teaspoon is plenty. Taste before adding more; a powder this fine dissolves completely, so there is no undoing an overpour.
Where to get it
Every daily powder is 100% fruiting body. Here is what that means and how it differs from mycelium grown on grain, or read the rest of the guides.
