Your’s is my experience with my Ubileen that is starting to have substantial crops.
If I wait until I can “tip” them off the tree and until they have that blush they have in the Jung catalog picture, they ripen so fast I don’t know how to manage them.
You can’t tell they are ready (or even overripe as in your picture) by feel, even pushing on the stem end. When they are solid green, they are not ready, but if you leave them out that they start turning yellow, there is this very narrow window between a perfect pear and another blob to toss on the compost heap.
Help!
