What is puffed rice korean?

Puffed rice, also known as Tteokbokki in Korea, is a popular Korean snack made by puffing rice. The rice is heated, and the moisture inside the grain expands, causing it to pop. Puffed rice can be eaten on its own as a crunchy snack, or as a popular ingredient in many Korean dishes, including Tteokbokki, which is a spicy stir-fried rice cake dish. Puffed rice is also used in cereal bars and other snack products. It is a low-fat snack and is gluten-free and vegan-friendly, making it a popular choice for health-conscious snackers.
