Pease porridge in the pot, nine days old?

[megmaine]

Hello!
After learning the wonders of fermentation (got the Wild Fermentation book for Christmas, which was at the top of my wish list!) I want to ferment beans, but am nervous about just leaving them on the counter a few days after cooking.

Anyone have any methods for traditional bean ferments they could share? I'm remembering the song Pease Porridge Hot, and how some like it , "In the pot, nine days old!" and that sounds like natural fermentation to me!
