Mushroom Bisque With Farro

Preparation

1. Step 1

   Soak the farro in cold water for 1 hour, drain and set aside. Place the shiitake stems in a large pot, cover with cold water, cook over medium heat for 2 hours, drain and discard stems. Return the mushroom broth to a pot over high heat and reduce until it equals about 2 cups.

2. Step 2

   In a large, ovenproof pot over medium heat, melt the butter. Add the onion and cook until it begins to soften, about 3 minutes. Add the chopped shiitake and white mushrooms, the salt and pepper and cook, stirring frequently, until the mushrooms begin to soften, about 5 minutes.

3. Step 3

   Add the chicken and beef broths and simmer for 10 minutes. Add 1 cup of milk and the farro, stir, partly cover and continue cooking over low heat for 1 hour, stirring often to avoid sticking.

4. Step 4

   Remove half of the soup, process to a fine puree in a food processor in batches and then combine with the unprocessed soup over low heat. Adjust the consistency of the soup with more whole milk; the soup should be thick, but not globby. Adjust the seasoning with additional salt and pepper to taste. Serve garnished with a dollop of mascarpone, several grinds of fresh pepper and a sprinkling of fresh thyme.
