Bammy or bami is a traditional Jamaican cassava flatbread descended from the simple flatbread eaten by the Arawaks, Jamaica's original inhabitants. Today, it is produced in many rural communities and sold in stores and by street vendors in Jamaica and abroad.After bammy is made, it’s dried to preserve it so, when you buy bammy it’s hard. Before frying or toasting it you have to soak it in milk (usually coconut milk) or water. The flat, dry disks soak up all the milk or water and become plump.
