These are traditional ice cream sandwiches—typically consisting of ice cream between two chocolate wafer cookies—that have undergone a freeze-drying process. This process removes the moisture content, resulting in a dry, crunchy texture while preserving the sweet, creamy flavor of the original ice cream. Despite their dry texture, they melt in your mouth, providing a unique snacking experience.
The freeze-drying process involves several steps:​
Freezing: The ice cream sandwiches are frozen solid.​
Vacuum Chamber: They are placed in a vacuum chamber where the pressure is lowered below water's triple point.​
Sublimation: Heat is gently applied, causing the ice to sublimate—that is, transition directly from solid to gas—without passing through a liquid phase.​
Moisture Removal: The vaporized water is removed, leaving behind a dry, shelf-stable product.​
This method preserves the structure and flavor of the ice cream sandwich while eliminating the need for refrigeration.​
Freeze-dried ice cream sandwiches retain the original flavors of the ice cream and cookies. The texture becomes crunchy and airy, similar to a meringue or honeycomb candy. When eaten, they quickly dissolve in your mouth, releasing the familiar creamy taste of ice cream.
Originally created for astronauts to enjoy ice cream in space, these sandwiches have found a niche among:​
Campers and Hikers: Lightweight and non-perishable, making them ideal for outdoor adventures.​
Emergency Preparedness: Long shelf life makes them suitable for emergency food supplies.
Novelty Snacks: Popular in science museums and gift shops as a fun, educational treat.
