Dehydrated pears taste like candy.
You can dehydrate a couple of ways. I will usually load the dehydrator in the afternoon and let it run on a low temperature overnight. I( started this because it did not get in the way of whatever project I had planned for the day. I also have an out of the way place I can run it overnight without bothering me. Higher temos means shorter drying time and would probably work better for you. Dry to crispy and what is really important is to keep them in a sealed container afterwards or they will become chewy by picking up moisture from the air. Because I like my dehydrated fruit TOO much, I'll keep it in the freezer in a ziploc bag so I don't eat them all.
I am still using carrots, peppers, celery leaves and onions that I dehydrated a couple of years and, yes, they are great for soups!
Of all the paths you take in life, make sure a few of them are dirt.
