Cassava is a starchy, fibrous root vegetable found in South America and parts of Africa. The root is dried, peeled and then ground into a powdery flour. The result is a Grain Free, Gluten Free, Vegan, Dairy Free and Sugar-Free powder flour.   Cassava is believed to have been first cultivated by the Maya in Yucatán and has been used in cooking for over 4,000 years.  As a drought-tolerant crop, cassava can be grown on marginal soils and gives reasonable yields where many other crops do not grow well.  As a result, cassava root is now grown worldwide.
