Tapioca, also known as cassava root, is a starchy tuber native to South America and widely cultivated in tropical regions. It has a rough, brown outer skin and a firm white interior. Rich in carbohydrates, tapioca is a key energy source and is commonly used in a variety of dishes such as curries, fries, and traditional snacks. Once peeled and cooked, it becomes soft and mildly sweet. Tapioca is gluten-free and easily digestible, making it a popular choice in both everyday cooking and special diets.
