Notes
- Storage: Transfer the soup to an airtight container and store it in the refrigerator. It can be stored for 3 to 4 days.
- Japanese sweet potato skins are edible and packed with nutrients like other sweet potato varieties. While I usually cook them with the skins on, I peel them for this soup recipe to achieve a smooth, creamy white color.
- Soaking sweet potatoes helps remove any bitterness and prevents them from changing or darkening in color.
