Some of the cranberries are very watery inside instead of firm and solid. Does that mean they are past ripe and generally not eaten?

If cranberries are frozen then removed from the freezer then thawed, will have a soft texture and are very usable for cooking and baking. Adding frozen cranberries to receipes is often recommended. Cranberries that were recently purchased and never frozen that appear soft are past the ripened stage, these berries should be sorted and not eaten.
