Would you like to enjoy the same ice cream that was developed for NASA in the 1960s? Then try a freeze dried ice cream sandwich by the Astronaut Foods brand. It is a real, Neapolitan ice cream sandwich that needs no rehydration, no refrigeration, and has a 3-year shelf life. This freeze dried ice cream sandwich is made by freezing ice cream down to -40 degrees Fahrenheit, then vacuumed dried to remove more than 98% of the water. It comes in a one-ounce pouch that you can get in different sets and quantities, and there are plenty of other popular flavors to choose from.
