Kitchen Science: Sourdough Starter Day Three


Today things should be starting to pick up! You should be woken up to bubbles and even some movement. You may notice the starter crawling up and down the side of the jar. You will also start to notice a sweet and sour smell. This should not smell “bad’. If it does smell bad throw it out and start over. You may have accidentally grown bad bacteria. If you notice a liquid on top of your starter this is normal, just pour it off, the liquid is a sign that too much water was added at the last feed. Today we are going to start twice-a-day feeding. To keep things simple, I do this at 7:30am and 7:30pm. If this time frame does not work for you no problem, pick two times 12hrs apart that work well in your schedule.


Day three supplies:

  • Jar with starter

  • New clean plastic wrap

  • 1 cup of flour

  • ½ cup lukewarm filtered water

  • Non-metallic whisk

Step 5: Place new plastic wrap and set aside
