Many hachiya persimmon lovers have waited over a month for their persimmons to ripen. Some of the fruit ripens nicely, some don't. It's a test of patience.
Today, at the produce market at Geary and 4th (south east corner of intersection; I think the name is something like Farmer's Market), they were selling large, absolutely ripe, ready to eat hachiyas for $.69/pound! After I had 5 pounds in my basket, the nice produce guy told me he was putting out more, but the season is coming to an end. So run over there soon and feast on the hachiyas!
