Bulla is a starchy white powder, harvested in Ethiopia from the Enset plant.
To make it, the stem and leaf sheaths of the plant are scraped into a pulp. The juice is squeezed out of this, and the juice is then evaporated down to a white powder.
This powder can be stored for years. It is rehydrated with water to make dumplings, porridge, pancakes, or it can be made into a drink of the same name.
Also called “Atmit.”
