Tapioca flour is a gluten-free starch made from the cassava root, a plant native to South America. It is commonly used in cooking and baking as a thickening agent or to create a chewy texture in various dishes. This flour is popular in many cuisines, especially in Asian dishes like boba tea and mochi. It can also be used to make gluten-free bread, pancakes, and desserts, making it a versatile ingredient for those with gluten sensitivities or celiac disease.
