Tips to Freeze-Dry Like a Pro

No matter what food you decide to freeze dry, there are some techniques that will make sure your food comes out exactly the way you want. Follow these tips to produce pretty, flavorful, and healthy freeze-dried snacks.

  • Cut fruits and vegetables into evenly sized portions. If you plan to eat individual pieces one at a time, make sure that you settle on a size that you (and your family) can tackle in one bite.
  • Some foods may stick to the trays; so, if you wish you can use parchment paper, silicon mat, or dehydrating mats to line trays before placing the food to be dried.
  • Lay food in one, even layer before placing in the freeze dryer. This will ensure consistency and leave every piece perfectly ready for storage or use in a recipe.
  • Pre-freeze foods in your regular freezer. This is especially helpful when the dryer is on or when there is a great sale. You can freeze your abundance and run it through the freeze dryer when the unit is available. It’s also smart if you don’t have enough food to run the dryer and need to buy some time.
  • Foods that have a high sugar content or a thick membrane (like blueberries) can sometimes take longer to freeze dry. Think about the foods that take awhile to really freeze in your regular freezer and those are some of the foods that will take longer to freeze dry. So, foods such as ice cream, fresh pineapple pieces and juicy peaches may do better when you increase the freeze time to 12 hours  and the dry time to 12 hours.
  • If you plan to freeze dry ice cream, make sure to get high-quality brands. Some ice cream has air whipped into it and it crystallizes in your freeze dryer. It’s still edible, just not as pretty.
  • Foods that have a thick membrane make it difficult for moisture to be released. Cutting or exposing the insides of foods like blueberries, grapes and cherry tomatoes will make the freeze drying process go much smoother.

Whether you’re worried about wasting food or looking for quick, easy ways to eat healthy on the go or during outdoor excursions and camping trips, freeze drying is worth looking into. You’ll discover a whole new way to look at food and its longevity when you give freeze drying a try.

How do you do asparagus? Ours never turns out right. Longer freezing? Or longer drying time? Ours seems to shrivel up.

If the food shrivels, that is an indication that a longer freeze is a good idea. Additionally, we did a quick 2-3 minute blanch on our asparagus. Many customers prefer to freeze dry it raw.

First, do a quick blanch for 3-4 minutes and cut the corn off the cob. Then simply pile it the height of the trays. It is yummy as a dry snack or perfect rehydrated and used as fresh corn from the cob in soups, stews, or as a side dish.

Blanching helps keep the color of the freeze dried process and also will aid with quick rehydration. It isn’t something that must be done, but helps make for a better finished product. Vegetables that are purchased in the frozen at the store are typically blanched beforehand.
