The bean pods have been hanging around in the kitchen for a few weeks in their string bags. It is the ideal place because they keep getting bumped (either on purpose or accidentally) as people pass underneath. This ensures the air circulates between the pods. As the pods dry out they straighten out and start falling through the gaps in the string bag. Any fallen pods get returned to the top of the pile. Once they start to open up of their own accord it's time to take them down and pod the lot.
If you pod them before the pods have dried the beans are prone to mould. I think there must be some inhibitor in the pod lining that stops that.
The podded beans are popped in a jar for storage until required for Chilli con Beany or Bean Dip at a later date.
