Onion Pachadi is a tangy and spicy South Indian condiment made with onions, tamarind, and spices. It is a versatile dish that can be served as a side dish or used as a dip. The onions are sautéed until golden brown and then blended with tamarind pulp, red chili powder, and other spices to create a flavorful and aromatic chutney. This pachadi pairs well with rice, dosa, idli, or even as a spread for sandwiches.
