How to Make Freeze Dried Candy

Candy lovers are always on the lookout for new and exciting ways to enjoy their favorite sweet treats. One innovative method that has gained popularity in recent years is freeze-drying candy. Freeze-drying is a unique process that preserves the flavor and texture of candy while removing most of its moisture. In this comprehensive guide, we'll explore the world of freeze-dried candy, why it's a fantastic option for candy enthusiasts, and how you can do it at home without the need for expensive machinery.

What Is Freeze Dried Candy?

Freeze-drying, also known as lyophilization, is a method of food preservation that involves freezing the product and then removing the ice crystals through sublimation. Sublimation is the process of transforming ice directly into vapor without passing through the liquid phase. This method has been widely used in various food industries to extend the shelf life of products while preserving their flavor and nutritional value.

When it comes to candy, freeze-drying involves freezing the candy and then placing it in a vacuum chamber. In this vacuum environment, the frozen water inside the candy sublimates, leaving behind a crisp, airy, and freeze-dried version of the original treat. The result is a candy that retains its taste, color, and shape while having a light, crunchy texture.

Why Freeze Dry Candy?

Freeze-drying candy offers several advantages that make it a favorite among candy enthusiasts:

Intense Flavor 

Freeze-drying preserves the original flavors of the candy without the need for additives or preservatives. The absence of moisture intensifies the taste, making it more flavorful.

Extended Shelf Life

Freeze-drying removes moisture, which is a primary factor in food spoilage. As a result, freeze-dried candy has a longer shelf life compared to its regular counterpart.

Lightweight and Portable

Freeze-dried candy is lightweight and easy to carry, making it an excellent choice for on-the-go snacking or camping trips.

Unique Texture

The freeze-drying process creates a unique, airy texture that provides a satisfying crunch when you bite into the candy.

Minimal Nutrient Loss

Unlike traditional candy-making processes, freeze-drying retains more of the candy's original nutritional content.

What Kinds of Candy Can Be Freeze Dried?

One of the great things about freeze-drying candy is that it works well with a wide variety of candy types. Here are some popular choices for freeze-drying:

Fruit-Flavored Candies

Gummy bears, fruit chews, and fruit snacks freeze-dry exceptionally well. Their vibrant colors remain just as eye-catching as their flavors, making them not only a delicious but also visually appealing treat. Whether you're looking for a crunchy and convenient snack or unique garnishes for desserts, freeze-dried fruit-flavored candies offer a delightful burst of fruity goodness in every bite.

Chocolate Candies

Chocolate-covered candies, such as M&M's and chocolate bars, can be freeze-dried, resulting in a unique and crispy chocolate treat. The freeze-drying process preserves the rich cocoa flavor of the chocolate while creating a satisfying crunch that's truly addictive. Whether you enjoy them on their own or as toppings for ice cream and yogurt, freeze-dried chocolate candies offer a delightful contrast of textures and an indulgent chocolate experience like no other.

Hard Candy

Hard candies, including favorites like lollipops and Jolly Ranchers, are another fantastic choice for freeze-drying. When you freeze-dry hard candy, you'll be amazed at how the texture transforms from a solid, jawbreaker-like consistency to a light and crunchy delight. The vibrant colors and sweet flavors of hard candies are beautifully preserved during the freeze-drying process. These freeze-dried hard candies can be enjoyed as snacks or used creatively as cake decorations or ice cream toppings.

Chamoy Candy

Chamoy candy, known for its sweet, salty, sour, and spicy flavors, can also be freeze-dried to create a unique twist on this beloved Mexican treat. Chamoy-covered gummies, belts, or even chamoy-flavored hard candies are great candidates for freeze-drying. The freeze-drying process enhances the intensity of the flavors while maintaining the candy's distinct spicy and tangy notes. The result is a crispy, snackable version of chamoy candy that offers a delightful combination of textures and flavors. Experiment with different types of chamoy candies to find your favorite freeze-dried variation.

Sour Candies

Sour gummies and hard candies maintain their tartness and crunch after freeze-drying. The freeze-drying process actually enhances the puckering sourness of these treats, making them an irresistible option for those who love a tangy punch. Whether you're a fan of sour belts, Warheads, or any other sour candy, freeze-drying them adds an exciting twist that will awaken your taste buds with each crispy bite.


Taffy, known for its chewy and stretchy texture, can be transformed into a unique treat through freeze-drying. When you freeze-dry taffy, it undergoes a remarkable change, becoming light and crisp while preserving its delightful flavors. Saltwater taffy lovers will appreciate the twist that freeze-drying adds to this classic candy. The result is a crunchy, airy version of taffy that offers a delightful contrast to its original chewiness. Freeze-dried taffy can be enjoyed as a nostalgic snack with a twist or used creatively in desserts to provide a surprising crunch.


Gummies, with their fruity and chewy appeal, are another candy variety that takes on a whole new dimension when freeze-dried. Freeze-dried gummies maintain their vibrant flavors while acquiring a delightful, crunchy texture. Whether you're a fan of gummy bears, gummy worms, or any other gummy candy, freeze-drying enhances their taste and creates a unique snacking experience. Enjoy freeze-dried gummies on their own as a crunchy treat or use them as creative toppings for ice cream, yogurt, or desserts. Experiment with different gummy flavors and shapes to find your favorite freeze-dried gummy delights.

Dry Ice vs. Freeze Drying Machine

Before we delve into how to freeze-dry candy without a machine, it's important to understand the alternatives. Two common methods for DIY freeze-drying at home involve dry ice and freeze-drying machines.

Dry Ice Method

Using dry ice for freeze-drying candy is a more accessible and budget-friendly option. Here's a simplified overview of how it works:

  • Preparation: Begin by placing your candy on a tray or cooling rack. Make sure the candy is spread out evenly, with space between each piece.
  • Freezing: Crush dry ice into small pieces and place it in the bottom of a well-insulated cooler or a Styrofoam container.
  • Candy Placement: Put the candy tray or rack above the dry ice, ensuring that it does not touch the dry ice directly. Seal the container, leaving a small gap for air to escape.
  • Wait and Monitor: Allow the candy to sit in the container for several hours or overnight. Monitor the process, and when the candy appears freeze-dried, remove it from the container.

This method works well for small batches of candy and is suitable for beginners.

Freeze Drying Machine

Freeze-drying machines are a more expensive but efficient option for larger quantities of candy. These machines automate the entire freeze-drying process, making it easier to achieve consistent results. If you have access to a freeze-drying machine, follow the manufacturer's instructions for candy freeze-drying.

How to Freeze Dry Candy Without a Machine

Now, let's explore the step-by-step process of freeze-drying candy at home without a machine using the dry ice method:

Materials You'll Need to Freeze-Dry Candy 

  • Candy of your choice
  • Dry ice (usually available at grocery stores or ice suppliers)
  • Styrofoam cooler or well-insulated container with a lid
  • Cooling rack or tray
  • Parchment paper or silicone baking mat
  • Oven mitts
  • Tongs
  • A well-ventilated area or outdoor space

The Freeze-Drying Procedure

1. Prepare the Candy

Choose your favorite candy or candies to freeze-dry. Arrange them on a cooling rack or tray lined with parchment paper or a silicone baking mat. Ensure that there is some space between each piece for even freeze-drying.

2. Crush the Dry Ice

Using safety precautions (wear gloves and eye protection), crush the dry ice into small pieces. You can use a hammer or mallet for this purpose.

3. Set Up the Container

Place the crushed dry ice at the bottom of the Styrofoam cooler or well-insulated container, creating an even layer.

4. Position the Candy

Carefully place the candy-filled cooling rack or tray above the dry ice. Make sure that the candy does not touch the dry ice directly. Seal the container, leaving a small gap for air to escape.

5. Wait and Monitor

Allow the candy to sit in the container for several hours or overnight. Keep an eye on the process to ensure that the candy is freeze-drying properly. You'll notice the candy becoming lighter and more porous as it loses moisture.

6. Remove and Enjoy

Once the candy has reached the desired level of freeze-drying (typically after 12-24 hours), carefully remove it from the container using tongs or oven mitts. Transfer the freeze-dried candy to an airtight container for storage.

7. Seal and Store

Store your homemade freeze-dried candy in an airtight container to maintain its crisp texture and flavor. Enjoy your unique and crunchy candy treats whenever you like!
