Mushroom Stock

Preparation

1. Step 1

   Heat the oil in a large stockpot or kettle set over medium heat. Add the onion, carrots, celery and garlic and cook, stirring frequently, until the vegetables are lightly browned, about 5 minutes. Add the mushrooms, dried porcini, thyme, bay leaf, peppercorns and 14 cups of water and bring to a boil. Adjust the heat and simmer gently, uncovered, for 2 hours.

2. Step 2

   Pour the stock through a fine-mesh strainer. Press down on the solids to extract as much liquid as possible. Stir in the soy sauce. Use as a base for soups and stews, or add more soy or tamari to taste and serve as a broth.
