A very sweet Bajoran confection made from the sap of the jumja tree and served on a stick, sold from a kiosk on the Promenade of Deep Space Nine.
The jumja stick is a Bajoran treat, a glazed lump of boiled tree sap that is eaten rather like a lollipop. A stall on the Promenade sells them, and they are seen in the hands of residents and visitors throughout Deep Space Nine.
The sweet is a favourite of many Bajorans on the station, and of Jake Sisko and Nog as boys. In the first-season episode In the Hands of the Prophets, the Bajoran vendor at the kiosk refuses to serve the O'Briens during the row over what Keiko teaches in the station school.
Like raktajino and hasperat, jumja sticks are a recurring small detail of station life rather than a plot element, used to make the Promenade feel like a working market.
