Purees are some of the easiest things to freeze-dry because they spread evenly. Applesauce turns into a crisp, light sheet that breaks into chips, or into neat drops if you pipe it. Ground into powder, it gives a quick apple flavor to oatmeal and baking.
Store-bought unsweetened applesauce is the simplest. Homemade sauce from a bushel of apples is the best use of seconds and bruised fruit.
Prep and loading
- Spread on a lined tray no deeper than ½ inch, or pipe small dots with a zip bag with the corner cut off.
- Silicone candy molds make uniform shapes; fill them and freeze before loading.
- Pre-freeze the tray; liquids spill easily when sliding into the chamber.
How to tell it’s done
- The sheet is dry and crisp all the way to the liner, with no darker, damp patch underneath.
Not sure? The weight check compares two weighings and the expected dry weight for applesauce.
Problems and fixes
The bottom stayed damp
Spread was too deep. Keep it to ½ inch, or flip the sheet and give it a few more hours.
Sweetened sauce went sticky
Added sugar slows drying. Use unsweetened sauce or load less.
Rehydrating and storing
Rehydrate: Stir 1 part powder into about 7 parts water by weight. By weight, 100 g of dried applesauce takes back about 708 g of water to return to fresh weight; the rehydration calculator does any amount.
Store: Mylar or jar with an oxygen absorber.
Ways to use it
- Drops and chips as a snack
- Apple powder for oatmeal and baking
- Rehydrated sauce on camping trips
How much fits per batch
At a normal single layer, applesauce load at roughly 2.6 lb of fresh food per square foot of tray. That works out to:
| Machine | Fresh per batch | Dried per batch |
|---|---|---|
| Harvest Right Countertop 360 | 6.5 lb | 12.8 oz |
| Harvest Right Small | 7.8 lb | 15.5 oz |
| Harvest Right Medium | 12.2 lb | 1.51 lb |
| Harvest Right Large | 20.0 lb | 2.47 lb |
| Harvest Right X-Large | 40.6 lb | 5.03 lb |
