Having set up shop in 2007, Blue Marble qualifies as virtually ancient among New York City's artisanal ice-cream shops. After generating serious buzz at Brooklyn Flea, that mecca of everything handmade, it set up shop at brick-and-mortar locations in Brooklyn. The milk comes from in-state farmers, flavors are all-natural and none of the ice cream contains corn syrup or preservatives. Interesting varieties include Grape Nuts and Cinnamon. Blue Marble's earth-friendliness doesn't stop at the ice cream itself: the stores' energy is provided by wind and water power, and the cups and spoons are compostable. Countertops are made from recycled materials, and the proprietors selected materials from Brooklyn's own Bettencourt Green Building Supplies to avoid the use of chemicals and minimize their impact on the environment.
