Keeping ripe pears for canning later
You could put them in the fridge, and hope they stay good, or you can blanch them and freeze.

Blanching:


Prepare the pears just like you would for canning (peel &amp; cut).
Dip the pear in hot water (or water with sugar) for about a minute.
From the hot water, dip into an ice-bath.
Plastic bag/container and into the freezer.
