How to Make It
- 2 cups water into a Dutch oven; add steamer basket. Add sweet potatoes to steamer basket. Cover and bring to a boil over medium-high. Steam potatoes until tender, about 30 minutes. Remove sweet potatoes from pot; rinse under cold water until cool enough to handle. Slice to remove small ends of potatoes; peel potatoes. Cut potatoes into roughly 1- to 1 1/2-inch rounds. Place sweet potato slices on a platter, and sprinkle with 1/2 teaspoon salt.
While sweet potatoes steam, heat coconut oil in a large skillet over medium-high. Add mustard seeds; once they begin to sputter, reduce heat to medium, and add onion, curry leaves, cinnamon sticks, pandan, and ginger. Cook, stirring often, 5 minutes. Add banana pepper; toss until slightly softened, 3 to 5 minutes. Add turmeric, red pepper, remaining 1 teaspoon salt, and remaining 1/2 cup water. Stir well until slightly thickened, about 1 minute. Pour onion mixture over sweet potatoes; squeeze lime wedges over potatoes, if desired.
