I ordered a dehydrator a few days ago. In light of the current pandemic, Amazon states delivery time would be in excess of a month. In reality, in only took a couple days. I put it to work immediately with some apples. 
They turned out pretty magnifico, but the lesson learned was to cut them consistently thin. After the first apple cut, I used a guillotine and that made things much easier.
Dried apples make enjoyable snacks and a much healthier option than what I normally snack on.
After the fruit, I moved on to try my first batch of beef jerky. That was my primary motive in ordering the dehydrator. First-world beef jerky is ridiculously expensive. So making it yourself for a substantial reduction in cost was too attractive to pass up.
I bought a kilo of beef bottom round as it was one of the more affordable options and a quick google search at the store led me to the conclusion it was also one of the best cuts you can get for jerky.
I marinated the meat with whatever I could find in the fridge. Terriyaki, soy sauce, and lots of salsa with chiltepin. As with the apples, the challenge was to cut the meat thin enough. I froze the meat for about 20 minutes to make it easier, but it was more difficult than I realized. As such, there were quite a few pieces that were too thick.
Overall I’d say it was a success, but given my lack of will power, I ate half of it in about 10 minutes which made me feel a bit sick and no longer wanting any more beef jerky any time soon.
Today I plan on trying some fruit leathers (as they’re called), which is just blended fruit poured out into the dehydrator and dried to make what is essentially a fruit roll up. I always loved those in my earlier years, but they were always expensive, so it was not a regular option.
