Equipment

  • 1 Ice Cube Mold

Materials

  • Sourdough Starter (100% peak hydration)

Instructions

Glass Jar

  • Place active sourdough starter in a glass jar and place within freezer in 1 to 5 ounce increments depending on preference. If filling glass jar, fill up to 80% maximum to ensure optimal space for expansion when freezing (so the jar does not explode within the freezer).
    If you have dried sourdough starter, you can also freeze this in a glass jar and place within the freezer to extend shelf life.
    Store in freezer until ready to use. When ready to use, allow to thaw at room temperature. Feed 1:1 ratio of sourdough starter, water and flour before using in your favorite sourdough recipe!

Ziplock Bag

  • Place active sourdough starter in a ziplock bag. Can store in 1 to 5 ounce increments depending on preference.
    Store in freezer until ready to use. When ready to use, allow to thaw at room temperature. Feed 1:1 ratio of sourdough starter, water and flour before using in your favorite sourdough recipe!

Ice Cube Trays

  • Place active sourdough starter in ice cube trays. Allow to freeze. Once frozen, remove cubes from tray and place within a ziplock baggie or airtight container. Take note on size of cubes (IE 1 ounce vs. 1.5 ounce) and mark ziplock baggie with date stored.
    Store in freezer until ready to use. When ready to use, allow to thaw at room temperature. Feed 1:1 ratio of sourdough starter, water and flour before using in your favorite sourdough recipe!
