A thick, frosty blueberry shake made with frozen kefir cubes and spicy fresh ginger. The kefir cubes, which make the smoothie cold and creamy without watering down the flavor like regular ice cubes, can be made in advance and stored in a ziploc freezer bag.

Note: Be sure to select plain, whole-milk kefir to make the kefir cubes. This recipe makes five kefir ice cubes, enough for one drink; if you're making more than one smoothie, be sure to make the number of kefir cubes you need.
