Pour into three serving cups and add ¼ teaspoon Nigari Tofu Coagulant to each cup and mix briefly.
Place into a dry box with a lid. Pour hot water into the box around cups, to level of soy milk. Cover and let sit for 5 - 10 minutes. Once set, remove cups from box.
Top the tofu with warmed greens and roasted mushrooms, and serve immediately.
