>I was surprised they didn't try sprouting the beans before cooking. When a bean germinates, it converts sugars in storage forms to more usable forms.

I always assumed that was the point of the overnight soak, although I often do the 'quick soak' method that most bean bags describe where you bring them to a boil and then turn the heat off and let them soak for an hour before draining and cooking.
