Oyster mushroom is considered netural and yin-nourishing in TCM food therapy. It has a great meaty, juicy texture when roasted in the oven. In this recipe, the mushrooms are coated with a rich sauce made from extra virgin olive oil, soy, and Five Seasons TCM Kidney Nourishing Powder that consists of black soybean, black sesame, and black wood ear mushroom. The end result is a creamy, nutty, fulfilling plate of roasted mushrooms that nourishes kidney yin.
