But I was keeping quiet, knowing some people would say the same about my plant-based diet.

But it may be a good solution if you can't buy or prepare fresh food? It's not really any different than Aseptic packaged foods, or canned foods. Just another way to preserve.

That freeze-dried ice cream reminded me of some stuff (they called it ice cream) that was served at a wedding I attended, it didn't melt no matter how long it was left out. I suppose that's good for catering halls that have to prepare hundreds of dishes, but it's probably not good for the guests.
