Hey there, been a bit.
After trying multiple times and for long periods to get a starter started, I finally hit on a success. I used SourdoLady's Pineapple Starter recipe (except I used OJ) and, lo and behold, foaminess overflowing!! Literally. Twice, even. So after cleaning up the goo off the counter for the second time, it was time to bake up my fist loaf of actual sourdough bread. I know, this is a rather immature starter but IT'S ALIVE!!
