My pear tree was loaded with fruit this year, but the skin on the fruit was tough and blotchy--perfect for fruit leather.
We washed them and cut them into fourths. I put water into a large, heavy-bottomed pan--just enough to cover the bottom-- filled it with my fruit, and put the lid on. The water helped to steam the pears; the heavy bottom helped to keep the fruit from sticking or burning on the bottom of the pan. I stirred it frequently, rubbing the big spoon across the bottom to be sure nothing was sticking, and I stirred the fruit near the bottom up towards the top, allowing all the fruit to be evenly steamed.
When the fruit was soft, I allowed it to cool slightly and then I put them through a fruit strainer. Mine is an attachment to my KitchenAid mixer; the skins, seeds, and cores come out one end while the fruit pulp slides out the bottom. It looked just like applesauce.
There are many kinds of strainers (some electric, some not), but if I needed to make the pulp without one, I'd peel the fruit and cut out the cores prior to steaming. When it was soft, I'd either mash it really well with a potato masher or run it through the blender just long enough to remove the chunks.
Since these pears were exceptionally juicy, I chose to simmer the sauce until it was thick. I took this time to bring my dehydrator up from the basement, clean it up, and get it ready. I have a wonderful machine--it is an Excalibur. It has a nice range of temperature settings, pulls the air across the sheets horizontally (if it pulls the air through the fruit vertically, the moist air travels through each layer of fruit, making it much less efficient), has sheets for fruit leather, and is large enough for my needs.
By the way, if you are making fruit leather from berries and soft fruits, it is possible to puree them and put them directly into the dehydrator. Fruit that turns dark when sliced, though, is usually heated to 190 degrees prior to drying.
When the pulp was ready, I ladled it onto the dryer sheets and smoothed it out--trying to make it about 1/8 inch thick in the middle and 1/4 inch on the sides.
It took about 24 hours at 135 degrees for the pulp to dry down to a leathery sheet. I tested it by touching it in the middle to see if it was tacky, then I peeled it off the dryer sheets and turned it over to see how it felt on the bottom. When it felt dry, I cut the leather into squares with a kitchen shears--one batch must have been thicker than the other because I noticed it was spongy as I tried to cut it; that sheet went back into the dryer for a few more hours. To keep the pieces from sticking to each other in storage, I placed the squares into a large plastic bag filled with a small amount of powdered sugar and shook them until they were covered. My children complain that his makes them messy (although this never stops them from eating it); I don't know how much the pieces would stick together if allowed to sit in a container for a long time without the coating. I've never tried that.
A couple of pieces on the tray above have obviously tangled with some of the powdered sugar.
I filled a couple of half-gallon plastic freezer containers with the leather, but I've read that many people use canning jars with lids and rings to store them so that they are certain to keep the moisture out. My leather never sticks around long enough for me to worry about that!
The fruit leather is tough and hard to chew, but I've had to hide some of it so that it does not completely disappear in just a few days! When I apologize for its being too tough, everyone responds, "It tastes great!"
If you stop by to visit, I'll offer you a piece, but you will have to do it soon!
