These sweet potato dumplings are a delightful twist on traditional veggie dumplings. The sweet potato filling is cooked until tender and mashed, then combined with sautéed onions, garlic, and spices. The dumplings are steamed to perfection in the Thermomix, resulting in a soft and fluffy texture. Serve these dumplings with a tangy tamarind dipping sauce for a unique and flavorful dish.
