The Cavaell system is where the cookies called Cavaellin creams originated. While working at Maz Kanata's castle on Takodana, the Artiodac chef Strono Tuggs obtained the cookie recipe from an aged 434 unit. Tuggs later revealed the location of their origin in his cookbook, The Official Black Spire Outpost Cookbook, published after the Battle of Takodana in 34 ABY; his recipe was for Cavaellin Spice Creams.
The system of Cavaell was added to the new Star Wars canon through the 2019 cookbook Star Wars: Galaxy's Edge: The Official Black Spire Outpost Cookbook, which was written by Chelsea Monroe-Cassel along with Marc Sumerak. The Cavaell system, in the Star Wars Legends timeline, was initially referenced in The Essential Atlas, a 2009 reference book authored by Daniel Wallace and Jason Fry.
