Follow the Sourdough - Day 1: Can you say Lactobacillus Sanfranciscensis?

I'm making sourdough bread, and I thought that some of you would like to follow along in real time. So, I will be doing a multiple-day, multiple-post sourdough bread recipe. I'm in the process of filming a sourdough video recipe for About, which will be covered in one 3 minute clip, but for you food wishers (that's what I call you behind your backs), I thought a clip-by-clip presentation would be more fun and informative.

Here is day one's step; starting the "starter." As you'll see, it is very basic, and requires only bread flour and water. The magic of sourdough is this "starter," with is basically a living, fermented batter that is made possible from the reaction between wild yeast in the air and Lactobacillus bacteria. These two live in symbiotic bliss and prevent any other microorganisms from growing in the starter. Good luck and stay tuned for the next video. Enjoy!

Tip: Use an unbleached bread flour for best results
