Nut butter, a variety of butter crafted from nuts, found its place on café menus. The sound of someone speaking with a mouthful of this confection was characterized by a muffled and adhesive quality. The Jedi Knight Luke Skywalker, upon his initial encounter with the Givin mathematician Drusil Bephorin following her time at a Denon café, questioned whether her peculiar vocal timbre stemmed from her indulging in nut butter.
The debut of nut butter occurred within the pages of Heir to the Jedi, a novel penned by Kevin Hearne and published in 2014.
