Chang is Thai for Elephant and the name and logo are instantly recognisable on bags of grain - a sign of quality. Tapioca flour is a popular gluten-free flour alternative that is made from the starch of cassava root. This species is native to the northern region and central-west region of Brazil, but its use spread throughout South America before colonists brought it to the West Indies and Southeast Asia. It is perfect for producing gluten-free baked treats or as a thickening agent in soups, sauces, and stews.
