Homemade Vegetable Broth
- Heat the oil in a large stockpot over medium-high heat. Add the onions, carrots, celery and mushrooms and cook, stirring now and then, until browned in spots.
- Add the leek, garlic and tomato paste and stir until the paste darkens a shade.
- Pour in the water and add the parsley, thyme, bay leaves, peppercorns and salt. Bring to a boil, then lower the heat to a gentle simmer.
- Simmer uncovered until the vegetables are very soft and the broth tastes full.
- Pour the broth through a fine-mesh strainer into a large bowl, pressing lightly on the vegetables, then throw the vegetables away.
- Stir in the soy sauce if using and taste for salt. Cool the broth, then refrigerate it within 2 hours.
