Red rice murukku is a variation of the traditional South Indian savory snack known as murukku, which is made using rice flour. Instead of using regular rice flour, red rice flour is used in this recipe. Red rice is known for its nutty flavor and its high nutritional value. The dough is made by mixing together red rice flour, urad dal flour, butter or ghee, and salt. The dough is then shaped into small, spiral-like shapes and deep-fried until golden brown. The result is a delicious and crispy snack that is perfect for munching on any time of the day.
