Preparation
Step 1
Heat the oil in a heavy 6-quart pot over low heat, and add the onions, ginger, garlic, 1 teaspoon salt, and 1/4 teaspoon pepper. Cover and cook slowly until the onions are soft but not browned, 20 minutes or longer.
Step 2
Add the wine and cook, uncovered, for 5 minutes, until slightly reduced. Add the sweet potatoes, 5 cups water, and the sake, mirin, cream, and 2 teaspoons salt. Cover and simmer until the sweet potatoes are half-tender, about 6 minutes. Add the apples and cook until both the apples and the potatoes are tender, about 10 minutes. Remove from the heat, add the miso, and puree in batches in a blender, or in the pan using an immersion blender. Adjust to the desired thickness with water, and check the seasoning before serving.
