This soup comes together in a snap and is elegant enough for company. For extra flair, use homemade Citrus-Scented Silken Tofu. When making the soup with vegetarian dashi, tester Susan Pi doubled the miso.
2. Transfer the rice gruel and edamame to a blender. Add the miso and blend until smooth. Add the dashi stock and continue blending to incorporate the liquid well. Taste and add extra miso or dashi if you want a more savory flavor or thinner soup, respectively. Pour through a mesh strainer positioned over a bowl or saucepan; stir to facilitate straining. Discard the solids. Cover and refrigerate up to a day in advance. You should have about 3 cups.
3. The soup may be served cold, warm, or hot. If you are serving the soup warm or hot, bring the tofu to room temperature or warm it by letting it sit in hot water for about 10 minutes. Regardless, cut the tofu into 4 to 6 blocks (one for each serving); use a crinkle cutter if you want pretty ridged surfaces. Place each block of tofu in a shallow soup bowl, then ladle the soup around it. Top the tofu with the garnish of your choice and serve.
