Combine the water, tea powder, garlic, ginger, peppercorns, onions and mushrooms together.
Place on the stovetop at medium heat and allow the soup to gently simmer for at least 20-25 minutes. Do not bring to a boil.
After the first 20 minutes, add in the spinach and a good sprinkling of SPRIG Sichuan Pepper and Sea Salt and let the spinach gently cook for another 5 to 10 minutes.
Remove from the stove and serve with a drizzle of SPRIG Toasted Sesame Oil on top.
