UNCLE BILL'S FRENCH MUSHROOM SOUP

Steps:

• Rinse both mushrooms in cold water and immediately pat dry with paper towels.
• Cut mushrooms into quarters and then slice thinly, 1/8 inch thick.
• In a large heavy bottom soup pot, melt butter on medium heat.
• Add mushrooms and saute for 5 to 6 minutes or until liquid from the mushrooms has mostly evaporated.
• Sprinkle flour over mushrooms and cook for 1 minute, stirring often.
• Gradually stir in chicken broth, water and chicken soup base and bring to boil, about 5 minutes, stirring often so the bottom does not burn.
• Add thyme, bay leaf and green onions.
• Reduce heat, cover and simmer for 20 minutes.
• Remove bay leaf and discard.
• In a mixing bowl, whisk together egg yolks and whipping cream.
• Slowly add 1 cup of hot broth mixture from the soup pot to the egg/cream mixture, whisking constantly until incorporated. This prevents the egg yolks from cooking.
• Return mixture to the soup pot, adding slowly and whisking all the time while adding.
• Heat over low heat until hot, about 5 minutes.
• Add white pepper to taste.
• Serve soup sprinkled with minced parsley.
