I'm impressed. Who would have thought you could catch wild yeast from the air to make bread? Not me! But you can. I did it and it made beautiful, sour dough bread. Here's what you do- sterilize a non metal bowl by pouring boiling water over it. Then mix a 1/4 cup flour (I use whole wheat) and a 1/4 cup water (filtered if possible). Cover with a breathable cloth and leave it sitting on your counter. Each day for seven days, switch it to a new, sterilized, non metal bowl and add a 1/4 cup flour and a 1/4 cup water. After seven days, you should have caught your yeast and your starter will be done.
Note: NEVER use metal bowls or utensils with your starter. Also, wild yeast is more prolific in some areas than others. So, you'll just have to give it a try to see if you can catch some.
My starter now lives in this home. Now that it's started, feed it each day and give it a new, sterilized home once a month. I wrote a date on mine so I wouldn't forget to give it a new home.

Note: You're ready to bake when you have 2 1/4 total cups of starter. You'll need 2 cups for the recipe and 1/4 left over to continue growing.
