Now that summer is here, people will again be filling their freezers with Popsicles and ice cream for a cool treat. But have you ever noticed that brittle layer of ice that builds up on foods sometimes when left in the freezer too long?
It’s pretty gross and basically ruins the food for good. But why wonders Minute Earth? Sublimation. The water moisture in the food actually exits and freezes on the outside. Kind of like freeze drying your food.
