What are Freeze Dried Marshmallows?

Freeze dried marshmallows are a delightful treat that undergo a special drying process to remove their water content. This results in a crispy, airy texture that's packed with flavor. They are commonly found in cereal boxes, but did you know you can make them at home too?

Why Freeze Dry Marshmallows?

Freeze drying marshmallows not only gives them a unique texture, but it also extends their shelf life. Perfect for those who can't get enough of these fluffy sweets but hate how they tend to get soggy over time. With freeze drying, you can enjoy your marshmallows anytime you want without worrying about them going stale.

The Process of Freeze Drying Marshmallows

Equipment Needed

The primary equipment needed to freeze dry marshmallows is a freeze dryer. Among the most popular models is the Harvest Right Home Freeze Dryer.

Step-by-Step Guide to Freeze Drying Marshmallows

Freeze drying marshmallows is simpler than you might think:

  1. Lay some Harvest Right Silicone Mats on the trays to prevent the marshmallows from sticking.
  2. Spread a couple of bags of mini marshmallows on each tray.
  3. Stick the trays in the Harvest Right Home Freeze Dryer.
  4. Set the parameters on the freeze dryer. Select "Non-Liquid" and "Non-Frozen."
  5. Start the freeze dryer and wait.

Timing and What to Expect

The freeze-drying process takes around 36 hours. Be sure to be around when the marshmallows are done being freeze dried, as they will need to be moved into sealed containers for long-term storage. The longer they sit out, the more moisture can re-enter them, lessening their shelf life.

Storing Freeze Dried Marshmallows

Packaging for Short-Term Storage

For short-term storage, you can place the freeze dried marshmallows in a mason jar with an oxygen absorber.

Packaging for Long-Term Storage

For long-term storage, store the marshmallows in Mason jars with an oxygen absorber. After filling the jars, vacuum seal them using a Foodsaver Vacuum System, along with a Foodsaver Mason jar attachment. Label the jars with contents and packing date, and store them on your long-term storage shelves. This way, your freeze dried marshmallows can last up to 25 years.

Using Freeze Dried Marshmallows

Incorporating into Recipes

Freeze dried marshmallows are a fantastic addition to various dishes. They can be tossed into hot cocoa or sprinkled over a baking sweet potato pie. They also work great in any baked dish that calls for marshmallows.

Reconstituting Freeze Dried Marshmallows

Reconstituting freeze dried marshmallows is as simple as adding them to a warm dish. The marshmallows will absorb the warm juices and regain some of their original texture.

Other Methods to Dry Marshmallows

If you don't have a freeze dryer, you can use a dehydrator, an oven, or even the sun and a freezer to dry your marshmallows. However, these methods may not provide the same shelf life as freeze drying.

Using a Dehydrator

To use a dehydrator, lay out your marshmallows on the trays, start the machine, and check your marshmallows regularly. Once they're to your liking, move them into sealable containers for storage.

Using an Oven

To dehydrate marshmallows in the oven, set your oven as low as it will go and place your marshmallows on a tray. The key here is to avoid melting or burning the marshmallows.

Sun and Freezer Drying

To sun dry, place your marshmallows on a tray and leave them outside in a sunny spot until they are to your liking. For the freezer method, put your marshmallows in a container or bag and place it in the freezer. Check on them after two weeks and move them to a sealed container for storage if they are done.

The Joy of Homemade Freeze Dried Marshmallows

Whether you're using them for your morning cereal, your hot cocoa, or as a snack on their own, you're in for a treat.
