Ok, I know I didn't give yall much to work with. After looking at some variety pictures this looks and sounds most like a Bosoc. And the definition fits its also. This is by far the oldest pear tree I have ever seen. Ok, The outer bark is at least 3/4" thick. The trees bark, not the pear skin...LOL.
The peeled pear is crisp like a honey Crisp although I couldn't think anyone would pick one up and attempt to bite into it. Its extremely mild in pear taste. I make jelly, I make preserves, I am just not sure the flavor would be enough to carry thru. Sweets never a problem but flavor is.
Can you tell never much been around pears and these came from the neighbors tree which I have never seen fruit before.
Maybe that's why most preserve recipes for pears have added flavors like pineapple, honey, cinn., and ginger...... and now red wine. Maybe a mulled spiced red wine with pear?
