Sundakkai Vathal (dried turkey berry) is a traditional South Indian condiment made by soaking small, bitter turkey berries (Solanum torvum) in curd (yogurt) and salt, then sun-drying them until crispy. Commonly used in Tamil cuisine, these sun-dried berries are typically deep-fried or roasted to provide a bitter, crunchy contrast in dishes like Vathal Kuzhambu, sambar, or as a side with rice.
