Buttermilk plant went bad.

Toast
Really sour, like sour milk, so it had to be pitched.  I've e-mailed the Ballmaloe cooking school about this buttermilk plant and hope to hear from Darina Allen about this "plant."  When I do, I'll let you know.

My experiment didn't turn out well.  I was always stirring it, and I know you didn't, but, well,  so no curds formed and there were just a few specks of something after pouring very sour milk through a fine filter.  I added some milk to it and it just sits there now. 

Thanks in advance about the "plant" inquiry.
