Onion Masala Dosa is a popular South Indian delicacy that combines the crispy texture of dosa with a flavorful onion masala filling. Made from a fermented rice and urad dal batter, this dosa is spread thinly on a hot griddle and cooked until golden-brown. Inside, it features a delicious filling of spiced onions and potatoes. The onions are caramelized to perfection with mustard seeds, curry leaves, turmeric, and other spices, creating a savory and aromatic mixture. The potatoes add a hearty and satisfying element to the filling. Onion Masala Dosa is typically served with coconut chutney and sambar on the side. The coconut chutney provides a sweet and nutty contrast, while the sambar adds a tangy and spicy flavor. Together, they complement the crispy dosa and enhance its overall taste experience. Onion Masala Dosa is a favorite among dosa enthusiasts for its combination of textures and flavors, making it a perfect choice for breakfast, lunch, or dinner.
