Makes 1 gallon (about 8 servings) Some plant-based ingredients have many of the same collagen-promoting benefits as bones, including sea vegetables, soybeans, celery, beets, and greens. Mushrooms add both immune-supportive compounds and a rich, earthy flavor, and red miso provides probiotics and a deep umami flavor. Another appeal: while bone broths take at least 12 hours to cook, this quick, healing version is ready in little more than an hour. When reheating this broth, be sure to warm gently on very low temperature to avoid damaging the miso.
