Lyseed seasoning was a form of flavor enhancer. The droid chef BX-778 utilized a dash of lyseed seasoning when stir-frying Lee romay. Hondo Ohnaka, a Weequay, seasoned Blue Puff Cubes with lyseed seasoning; however, a Porg named Puffy pilfered his prepared food. Furthermore, lyseed seasoning was an ingredient in the seasoning of certain popped grains sold at Kat Saka's Kettle, which is located in Black Spire Outpost on the Outer Rim world of Batuu.
The canon novel Last Shot marked the initial appearance of lyseed seasoning. It was later introduced into the physical world for patrons of Kat Saka's Kettle within Star Wars: Galaxy's Edge at Disneyland in Anaheim, California around the beginning of January in 2025. The Lyseed Popped Grains snack's description on the menu disclosed that lyseed seasoning equated to "Dill Pickle Seasoning" in reality.
