It is common for the starter to take some time to get a good punch. If the bread tastes sour then there is lacto bacillus in it. Plain yogurt still has lacto bacillus so if it does not taste sour try that. Adding baking yeast will not work since baking yeast will not live in a starter. Potato flour is a good thing to use in the starter as well as in the bread. Just a table spoon or so. Also, it is a good idea to use milk instead of water when feeding the starter every once in a while.I suppose if you keep opening it weekly anaerobic bacteria isn't an issue. I've got some of those, even in a few sizes. In fact, that's what I used the last time I tried something similar, just don't leave it in your fridge for half a year, because I tell you, it gets a bit suspicious. It seems I have manage to capture some wild yeast in my starter, the dough I put together 5 hours ago has started rising. I'm going to try and make a rosemary bread in the morning, this time with a bit more rosemary in it. I hope the wild yeast will behave in the same way as dried yeast, because I really like making the no knead bread. It makes virtually no mess compared to the regular stuff that you need a flowered surface for and everything. I still need to up the time I preheat my pot though, because I still haven't gotten it to sizzle when I pour in the dough.
Only use luke warm water--85 Degrees F.
