Natural Yeast Starter

A while ago I found a couple recipes online from Bread and Cie, an amazing bakery only three blocks from my apartment. Of course, I had to try them out, but these are classy bread recipes. No powdered instant yeast for them. They want you to grow your own living yeast from scratch. Helpfully, a recipe for culturing yeast is provided, but it takes almost a week to complete and I've just now managed to get it all together. I'm about halfway through the process right now, so I wanted to post some pictures. I wish I'd remembered to take a picture before I'd thrown away the grapes (see recipe), but here's a picture of the yeast after it's been percolating for four days, and a second picture a few minutes later after I've given it its first feeding of flour and water. Tomorrow morning I'll transfer it to a larger bowl and feed it again. By tomorrow night, it should be big and bubbly enough to be turned into either Caramelized Onion Bread or Kalamata Olive Bread. Yum!
