Somebody asked me about using tap water to activate your Mister Sourdough starter. He wanted to know if it was really that bad. My answer is yes and no. It depends and where you live and the time of the year. When the weather is warm, cities tend to over treat. If you use tap water it may hinder or stymie the growth altogether. This is why I always suggest using either bottled or filtered water. If you use tap water, let it sit out for a few hours.
My son lives in San Jose, CA and he ignored my warning and killed his starter using tap water. Currently I am performing an experiment using Valentina's San Francisco Sourdough Starter by activating it with tap water. I have two containers, one is using straight tap water and the other filtered. Both seem to be doing fairly well after a day and a half. My tap water is from Northern Utah.
Bottom-line? Err on the side of caution. Use bottled water if you can, filtered if you cannot and straight tap water if there are no other options.
To simplify the updating process of my blog entries I have created a single ORDER page you can go to by clicking here. As the blog slowly grows in size (a few posts each month) it becomes an arduous labor updating each and every one of them so hopefully this will make the pages easier to peruse and more enjoyable. Thank you.
