Bhoonja is a traditional Indian snack that consists primarily of a mix of puffed rice, roasted lentils, peanuts, and various spices. Its origins are associated with the street food culture prevalent in various parts of India. Bhoonja is especially popular in regions like West Bengal, Bihar, Jharkhand, and Orissa, though its exact origins are not clearly documented. The dish is known for its crunchy texture and savory taste, often accompanied by a hint of spice.

Puffed rice, also known as "muri" in West Bengal, is a central ingredient in Bhoonja. The preparation often includes additional components such as sev (fried chickpea flour noodles), fried curry leaves, onion, and sometimes coconut pieces for added flavor. The combination is typically seasoned with salt, turmeric, chili powder, and optional lime juice, which enhances its flavors. Turmeric provides its distinct yellow coloration.

Bhoonja is usually prepared by dry roasting the ingredients, which contributes to its crisp texture. It is a vegetarian snack, which makes it suitable for a broad audience in India, where vegetarianism is widespread due to cultural preferences and religious practices.

The snack is typically consumed as an afternoon or evening snack and is commonly sold by street vendors. Bhoonja can also be prepared at home and is often enjoyed with tea. It is similar in some aspects to another popular Indian snack called Bhel puri, though the latter typically involves wetter ingredients like tamarind sauce and is considered more of a chaat than a dry snack.

Across regions, variations of Bhoonja exist, often incorporating locally available ingredients or specific spice blends. Despite its regional roots, Bhoonja now enjoys popularity across the country due to its affordability, easy preparation, and the balance of flavors it offers.
