How many starters have you had at one time?
A bit tongue in cheek, I know. (: I currently have 3 starters, all from different recipes, going (they're in my oven overnight, to combat the cold winter temperature drop). I have a SourDoLady OJ starter (my OJ has added calcium, so I don't know if this one's going to work), a firm starter a la Maggie Glazer, and a "seed" starter from a blog I follow (The Underground Baker - http://undergroundbaker.blogspot.com/).
The first one that makes it to completion gets to flavour my first sourdough loaf!
How many have you had going at once?
