Kothavarangai Vathal is a traditional South Indian ingredient made by sun-drying cluster beans (kothavarangai) to preserve their flavor and texture. Once dried, these beans are typically fried or added to tamarind-based gravies like kuzhambu, giving the dish a satisfying crunch and a slightly bitter taste. Known for their ability to enhance the richness of dishes, Kothavarangai Vathal is also used in stir-fries and other savory recipes, making it a versatile and delicious addition to South Indian meals.
