Like most living foods, the environment that they live in is very important. Keeping positivity, kind words, good music, other living foods, and joy in your home with help the process of making sourdough so much more successful. Don’t forget that this is not really an exact science. Weather patterns, extreme temperatures, environmental issues, and seasonal changes can all effect the process of growing a sourdough starter. It’s very nuanced. Get a feel for whether or not you really need to add water one day, or maybe you just need flour. Work with it. Be patient. Have fun.
