Freeze-dried cooked rice is homemade instant rice. It rehydrates in a few minutes with boiling water, which saves fuel when camping and time on busy nights. Leftover takeout rice is a perfectly good batch.
Brown rice has oil in its bran layer, which shortens its storage life compared with white rice. Wild rice and quinoa dry the same way.
Prep and loading
- Cook rice slightly firm. Cool it in the fridge so it is less sticky.
- Spread ½ inch deep and break up clumps with your fingers.
- Seasoned rice (Spanish rice, fried rice) works too, as long as it is not oily.
How to tell it’s done
- Grains are hard and separate; clumps break apart dry.
Not sure? The weight check compares two weighings and the expected dry weight for cooked rice.
Problems and fixes
Clumps stayed soft
Break clumps before loading, or crumble them halfway through the cycle if your machine allows.
Mushy after rehydrating
Too much water. Start with a little less than equal volumes and add more.
Rehydrating and storing
Rehydrate: Boiling water, covered, 5–10 minutes. By weight, 100 g of dried cooked rice takes back about 203 g of water to return to fresh weight; the rehydration calculator does any amount.
Store: Mylar or jars with oxygen absorbers.
Ways to use it
- Instant side dish
- Backpacking meals with chicken or beans
- Fried rice
- Soups
How much fits per batch
At a normal single layer, cooked rice load at roughly 2.2 lb of fresh food per square foot of tray. That works out to:
| Machine | Fresh per batch | Dried per batch |
|---|---|---|
| Harvest Right Countertop 360 | 5.5 lb | 1.80 lb |
| Harvest Right Small | 6.6 lb | 2.19 lb |
| Harvest Right Medium | 10.3 lb | 3.40 lb |
| Harvest Right Large | 16.9 lb | 5.58 lb |
| Harvest Right X-Large | 34.4 lb | 11.35 lb |
