We always peel our pears because the skins can become tough and bitter. I've not known anyone who left the skins on. Net
I peel. I dry with skin on, but I peel anything I can. Grandparents used to have a kind of pear they canned with skin on, but I can't find another tree like it. Pears turned yellow and had the smoothest skin, they were almost the shape of an apple too...
Around here, they call that an oriental or chinese pear. About the only kind that will grow here in the desert heat. G
