I think that's the hardest thing about pears. They say check the neck to see if it has softened, then lift it up gently and if it comes off easily, it will be good. I have found that's not always true. Once I did that and they never ripened. The next year (last year), I waited a couple of extra weeks and they ripened perfectly. I think it is useful to look at a chart, for when that type ripens for a location, and adjust it to your location. For this year in the Willamette Valley, we are a few weeks late, so we'll have to adjust it that way.
Maybe I'm just not sensing it correctly. Maybe I'll go to France, put on a beret, talk about mysterious things and become supremely sensual and then I'll know.
