Ice cream turns into a crunchy, melt-in-your-mouth block with all the flavor of the original. It is a crowd favorite, but it is not storage food: ice cream is around 10% fat and high in sugar, and both shorten how long it keeps.
The challenge is keeping it frozen while you load. Ice cream starts softening the moment it leaves the freezer, and any melting before the vacuum starts causes collapse and sticky spots.
Prep and loading
- Put the trays in the freezer for an hour first.
- Scoop small balls, or slice a pint or a block into ¾ inch slabs, working fast. Ice cream sandwiches cut into quarters work well.
- Return the loaded tray to the freezer until rock hard, then load.
- Leave space between pieces; they puff slightly.
How to tell it’s done
- Pieces are light and crunchy through the center.
Not sure? The weight check compares two weighings and the expected dry weight for ice cream.
Problems and fixes
Flat, gooey puddles
It melted before the cycle froze it. Freeze trays first, work fast and pre-freeze the loaded tray.
Stale taste after a few months
Fat oxidation. Make it in small batches to eat soon.
Rehydrating and storing
Rehydrate: Not rehydrated. Eaten as a crunchy treat. By weight, 100 g of dried ice cream takes back about 149 g of water to return to fresh weight; the rehydration calculator does any amount.
Store: Jars or mylar with an oxygen absorber. Best within a few months.
Ways to use it
- Treat and party snack
- Gift bags
- Crumbled over desserts
How much fits per batch
At a normal single layer, ice cream load at roughly 2 lb of fresh food per square foot of tray. That works out to:
| Machine | Fresh per batch | Dried per batch |
|---|---|---|
| Harvest Right Countertop 360 | 5.0 lb | 2.00 lb |
| Harvest Right Small | 6.0 lb | 2.42 lb |
| Harvest Right Medium | 9.4 lb | 3.77 lb |
| Harvest Right Large | 15.4 lb | 6.18 lb |
| Harvest Right X-Large | 31.3 lb | 12.57 lb |
