Freeze-drying proves to be an enjoyable family effort that everyone can engage in, so gather your favorite people and preferred sweets – let the fun begin!

What’s Freeze-Drying?

Freeze drying extends food shelf life by sucking out moisture. True freeze-drying demands a specific appliance, not just a freezer or dry ice setup. Texture plays a significant role in distinguishing standard candy from freeze-dried versions. This happens due to rapid freezing at extremely low temperatures, a familiar concept from high school chemistry – water expands when frozen.

Unlike their initial crunchiness, freeze-dried candies melt in our mouths. Freeze-dried candy’s mouth-feel differs significantly.

In freeze drying, food chills to temperatures between -58 and -112 degrees Fahrenheit, product-dependent. This freezes it into a solid state, distinct from gas or liquid. Subsequent drying occurs through pressure reduction and dual heat cycles. 

The outcome? Food with minimal water content and the easiest way to understand how to freeze dry candy at home. Unlike chewy heat-dehydrated food, freeze-dried delicacies effortlessly melt in your mouth.

  • Toss your preferred candy into freezer bags, loosely sealed, inside a cooler.
  • Let dry ice work its magic for 24 hours on a low-humidity day—don’t seal the cooler.
  • Open the bags, and transfer candy cautiously to new ones.
  • Stash in a cool, dry spot (pet and sibling-free zone) for a taste journey!
  • Properly freeze-dried DIY candy maintains its original color. 
  • To dehydrate candy using this technique, a specialized machine, a freeze-dryer, is essential. 
  • Sweets are arranged on trays within the freeze-dryer, initiating a temperature drop in the chamber. Ranging from -50°F to -30°F, these low temperatures ensure thorough freezing.
  • Achieving the desired low temperatures triggers the machine to create a vacuum within the chamber.
  • With reduced pressure, heat infiltrates the chamber. Due to low pressure, as temperatures surpass 32°F, ice crystals in the sweets don’t liquefy; instead, they evaporate.
  • While freeze-drying yields unique results, a drawback is the need for specialized equipment, namely a freeze-dryer machine. Given their potential cost, opting to buy ready-made freeze-dried sweets may be more practical for occasional consumption.

Tips for how to freeze dry candy 

  • When freeze-drying candy, avoid tray overload for an even outcome. 
  • Ensure sweets have ample space as some candies expand during this process.
  • Unwrap candies, and arrange them on parchment-lined trays, maintaining even distribution. 
  • Smaller candies freeze better; break up large ones if needed. Freeze the tray until the candies solidify.
  • Place the frozen candies in the freeze dryer, set the freezing temp to zero, and the drying temp to 135 degrees Fahrenheit.
  • Check for dryness; the candy should be dry, not sticky. If not, a second run in the freeze dryer works wonders. 
  • No worries about overdrying; moisture removal is the goal.
  • Let the dry candy rest at room temperature.
  •  Store in an airtight container with desiccant packets for extended shelf life. 
  • Keep them away from sunlight and moisture, just like other freeze-dried treats.
