MUSHROOM SOUP POWDER RECIPES

Steps:

• Coarsely chop the dried mushrooms or cut them into pieces with scissors. Working in batches, grind them to a fine powder in the spice mill. [Makes 1/2 cup (8 tablespoons) powder.]
• If time permits, combine the cream and 2 tablespoons mushroom powder in a jar, seal, and refrigerate for 24 hours to infuse the cream with the mushroom flavor and aroma. (Alternatively, combine the cream and mushroom powder in the heavy-duty saucepan, bring just to a simmer, cover, remove from the heat, and set aside for 30 minutes to infuse the cream.)
• At serving time, in heavy-duty saucepan, combine the infused cream, salt, and stock and bring to a gentle simmer over medium heat. Remove from the heat and taste for seasoning.
• Serve in the warmed soup bowls, garnished with chives and a drizzle of oil.
• The soup can be prepared up to 3 days in advance and stored in airtight containers in the refrigerator.
• Add sliced raw domestic or wild mushrooms to the soup and cook for several minutes; add grilled, sliced fresh cèpes or domestic mushrooms; add truffle matchsticks at serving time.

Steps:

• Melt butter in a large soup pot over medium-high heat; cook mushrooms in butter with 1 pinch salt until the mushrooms give off their juices; reduce heat to low. Continue to cook, stirring often, until juices evaporate and the mushrooms are golden brown, about 15 minutes. Set aside a few attractive mushroom slices for garnish later, if desired. Mix onion into mushrooms and cook until onion is soft and translucent, about 5 more minutes.
• Stir flour into mushroom mixture and cook, stirring often, for 2 minutes to remove raw flour taste. Tie thyme sprigs into a small bundle with kitchen twine and add to mushroom mixture; add garlic cloves. Pour chicken stock and water into mushroom mixture. Bring to a simmer and cook for 1 hour. Remove thyme bundle.
• Transfer soup to a blender in small batches and puree on high speed until smooth and thick.
• Return soup to pot and stir in cream. Season with salt and black pepper and serve in bowls, garnished with reserved mushroom slices and a few thyme leaves.
