Blue milk custard

Blue milk custard was a comfort food made using the blue milk produced by bantha species native to the planet Tatooine. It was served as a dessert at Old Jho's Pit Stop, a cantina on the planet Lothal run by the Ithorian Jho. The custard was one of the human Jedi Knight Kanan Jarrus's top five favorite desserts served in the establishment.
