Murmura, also known as puffed rice, is a light, airy, and versatile snack made by heating rice kernels under high pressure and steam, resulting in a crisp, low-calorie product popular in Indian cuisine for snacks like bhel puri and sweet treats. It's a good source of carbohydrates for energy, and often enriched with nutrients like calcium, iron, vitamin D, and fiber, making it a healthy choice for various dietary needs, though some users have noted packaging concerns.
