A sweetpuff jamwich was a kind of sandwich that was made by placing sweetpuff jam between two crackers and then cooking it over a fire. This sandwich gave off a sharp odor and could be eaten by both humans and members of the same species as the Jedi Master named Yoda.
While they were on the celestial body Endovar around 232 BBY, Yoda and Jedi Knight Kantam Sy prepared sweetpuff jamwiches. Yoda observed that the sweetpuff jam inside the sandwiches was on the verge of becoming excessively crunchy because Sy had kept them in the fire for an extended period. Once the sandwiches were taken out of the fire, Yoda, Sy, and the youngling Lula Talisola consumed them.
A flashback in The High Republic: Midnight Horizon, a young-adult novel from 2022 by Daniel José Older as part of the Star Wars: The High Republic multimedia initiative, featured sweetpuff jamwiches.
