Kitchen Science: Sourdough Starter Day Two


Welcome to day two of your sourdough starter. Don’t be alarmed if today is uneventful. Sourdough starters are like children, they grow at their own rate!

Today we are checking for signs of yeast growing. Grab your sourdough starter and check for bubbles. If you do see bubble “yay” you have yeast starting to grow, now you can follow the steps below.

If you do not see any bubbles, do not worry. Like I said starters are like children, they all grow and mature at different rates. Simply put aside and check in the evening, if you see growth then, “yay” you have yeast growing, now follow the steps bellow.

If no bubbles form just be patient, we will check again tomorrow!
