How to Create Sourdough Insurance


Keeping a sourdough starter can seem like a big commitment, but there are ways to manage sourdough better and make it fit your schedule.  

There is also a way to achieve a bit of sourdough insurance, to safeguard your favorite starter that has made the perfect loaf for you time and time again. By using the following method you can capture the symbiotic culture of bacteria and yeasts that make your particular sourdough starter fantastic.

Reasons for Dehydrating Your Sourdough Starter

Whichever of the above scenarios applies to you, be sure to implement your sourdough insurance sooner than later. Taking a bit of extra time now can save you regrets later on that you gave up your perfect sourdough starter.

How to Dehydrate a Sourdough Starter 

  1. Spread a bit of your fully active sourdough culture on a piece of parchment paper, a plate, or other flat surface.
  2. Leave starter to dry thoroughly. The starter is fully dried when it separates from the parchment paper or plate.
  3. Remove dried starter from the parchment paper. Crush or grind the now dried sheet of sourdough.
  4. Store in an airtight container in a cool, dry place. Refrigerator or freezer is fine for dried sourdough.
  5. This dried starter, if kept in the refrigerator or freezer, should keep for a year or more. See the directions on activating a dried starter when you want to put it back to use.
