I've been having some good luck with my dehydrating attempts, but hadn't yet tried to rehydrate anything. Today I finally gave in and threw a mixture of dried veggies into a bowl and covered them in boiling water. They came back perfectly, and a lot faster than I had anticipated. From everything I've seen and read, I thought it would take 15-20 minutes, but they were mostly ready in about 3.
I didn't do anything too exciting with them because I wasn't really prepared for it to actually work, so I just cooked up a small amount of rice vermicelli (takes 3 minutes) and added about 2 tsp of soy sauce and a drizzle of sesame oil. As far as camping goes, the only thing you probably wouldn't take would be the sesame oil, unless you had a really small squirt bottle and planned to use it in a few dishes. (I love the stuff, but the rest of the family isn't quite so enthusiastic)
This is something that is pretty simple though, and quick, so I'm going to work on ways of making a better sauce for it, maybe a thai curry sauce. You could also drizzle a bit of olive oil over it, and sprinkle some parmesan cheese on top.
The dried vegetables I used were:
orange pepper strips
tomato slices, broken into small pieces
The other day I made a really beautiful stir fry. It was super colourful and I really wish I'd taken a picture. Because I'd boughten some heirloom carrots, I changed things up and used a pale yellow carrot, an orange pepper, some broccoli, and some really pretty ruby chard. The stems were bright red and the leaves dark green with lots of dark purple. Of course, once I added the sauce, it wasn't so pretty, but still... I know it's possible to dry chard leaves, but wasn't sure about the stems. I'll have to look into that today and maybe do up the last of the bunch of chard before it goes bad.
More experiments coming soon. There's a pot of soup on the stove I'm going to dry a serving of, then rehydrate and see how that works out.
