MAKE THE MUSHROOM ESSENCE
Combine all the ingredients in a large pot and bring to a simmer.
Simmer for 45 minutes.
Strain stock and set aside until needed.
MAKE THE SOUP
In a large soup pot, melt the butter over medium heat and then add the garlic, onions, and celery and cook, stirring frequently until translucent, 5 to 7 minutes.
Add the mushrooms and cook until tender; about 5 minutes.
Sprinkle the mixture with the flour and mix well.
Add the sherry and mushroom essence and simmer, covered, until the mushrooms are completely tender, about 25 minutes.
Remove the soup from the heat and let cool for 5 to 10 minutes.
Puree the soup with a handheld blender, or in batches in a food processor or blender.
Strain the pureed soup through a colander or sieve. Reserved until ready to serve.
Once ready to serve, reheat the soup (if cooled).
In a small saucepan, gently bring the heavy cream to a simmer, then add it to the soup.
Adjust the consistency of the soup with a little more mushroom essence, if needed (it should not be thick or too creamy!).
Season with salt and pepper.
Serve the soup in warmed bowls and garnish with the chives and nutmeg.
