Blue milk

Blue milk, sometimes known as bantha milk and Tatooine milk, was a nutrient-rich blue-colored liquid produced by a female bantha's mammary glands. It could be found on most planets across the galaxy. Blue milk could also be fermented into an alcoholic version. The milk was also used to make a variety of yogurt, ice cream, and cheese, and it was rumored to have medicinal qualities. Its ubiquity inspired the military phrase "blue milk run." Dex's Diner served chilled blue milk in whole and short-wavelength varieties at a price of 1.5 credits for a small serving or 2.3 credits for a large.
