I've a bog-standard cheapo dehydrator which I use to dry fruit and veg in the summer and autumn when there's loads, especially when on offer. I live rurally and have been cut off by snow for five days and without power for three, on separate occasions. My hob runs on bottle gas so I can cook stews etc without electricity; I avoid opening the fridge and freezer so bottles of dried fruit and veg are handy to add to tinned and dry ingredients. I'm a vegetarian so I don't have to worry about keeping meat though I did live in a house as a child that had a meat safe outside.Aaaaand another thing. I have a dehydrator because I'm one of those vegans. I wouldn't be surprised if she had bought an Excalibur whilst in her vegan stage because there are some wonderful recipes out there and it's a popular thing in some vegan circles. They're expensive but I can definitely see it sitting under the sink now that grift is over.
I'm actually contemplating upgrading my life with a Ninja Foodi at Christmas, but I have to check if it'll allow me to part with the dehydrator I have because kale chips are an important part of my diet.
