Mushroom Consommé

Instructions

1. Prepare the mushroom base
   In a large pot, heat olive oil over medium heat. Add onions, carrots, and celery, cooking until softened, about 5-7 minutes. Add fresh mushrooms and garlic, cooking until mushrooms release their moisture and begin to brown, about 10 minutes.
2. Add stock and aromatics
   Pour in the vegetable stock, reserved porcini soaking liquid (being careful to leave any grit behind), and the rehydrated porcini mushrooms. Add the bouquet garni. Bring to a simmer and cook gently for 45 minutes to develop flavor.
3. Prepare the clarification mixture
   In a bowl, mix egg whites with 1 cup of the cooled mushroom broth. Set aside. Strain the remaining hot broth through a fine mesh sieve, pressing on solids to extract maximum flavor. Return strained broth to a clean pot.
4. Clarify the consommé
   Heat the strained broth to just below a simmer (around 180°F/82°C). Slowly whisk in the egg white mixture. Allow the egg whites to rise to the surface forming a 'raft' that will collect impurities. Maintain a very gentle simmer for 30 minutes without disturbing the raft.
5. Strain and finish
   Carefully ladle the consommé through a cheesecloth-lined sieve into a clean pot, being careful not to break the egg white raft. Season with salt, pepper, and lemon juice to taste. Gently reheat if necessary without boiling.
6. Serve
   Ladle the hot consommé into warmed bowls. Garnish with finely chopped fresh chives. For an elegant presentation, you can float a few thinly sliced mushrooms in each bowl.
