For lightweight camping food it would be nice to have rice that cooks quickly without using much stove fuel. Dried instant rice is available (example) but has some downsides: The flavours aren't great (and I find them unpleasantly salty); it's being displaced in the shops by microwavable rice which is much heavier as you're transporting water (it can be heated on a stove).
So I'd like to make my own dried instant rice - perhaps with some dried veg or spices mixed in. But rice is one of the worst foods for breeding nasties so I very much doubt you could just cook it and then put it in a dehydrator. The few ideas I've seen searching online are basically just freezing cooked rice, not dehydrating it at all.
Is there a sensible way to produce dehydrated instant rice at home?
