Manathangali (Black Night Shade Berry) VathalManathakkali Vathal is a traditional South Indian delicacy made from sun dried black nightshade berries (manathakkali). The fresh berries are soaked in buttermilk with salt, then dried under the sun to preserve their unique taste and healthful properties. When deep fried, Manathakkali Vathal turns crisp and releases a distinct, mildly bitter flavor that perfectly complements sambar, rasam, or curd rice. It is also a key ingredient in vatha kuzhambu,
