Tapioca chips, often called "maravalli" or "kappa" chips, are thin, crispy slices of cassava (tapioca root) that are deep-fried to create a popular South Indian tea-time snack. These round chips come in various flavors, including plain salted and spicy, and are known for their crunchy texture. They are a good source of carbohydrates and can be a gluten-free, vegan option, but they should be stored in an airtight container to maintain freshness
