Authentic Tamil Vatha Kuzhambu (with Sundakkai Vathal, Onion & Garlic) is a traditional tamarind-based curry that dates back centuries in Tamil Nadu, often prepared during harvest festivals and temple offerings. Its tangy and spicy profile reflects the Tamil palate's love for bold flavors, and the use of sundakkai (sun‑dried turkey berries) links the dish to ancient Ayurvedic practices for digestion.

In coastal districts like Nagapattinam, the curry may include fresh seafood and a higher proportion of tamarind, while inland areas such as Madurai often add extra black pepper and fenugreek for heat. Some versions replace sundakkai with dried gooseberries (nellikai) or add a handful of roasted peanuts for texture.
