SOURDOUGH STARTERS Storing the starter Starter will keep almost indefinitely in a clean, covered glass container in the refrigerator. Never use a metal container or leave a metal spoon in the starter or sponge. If unused for several weeks the starter may need to sit out an extra night before adding the flour and water. Drying the starter Sourdough starter may be dried for easy storing or sharing. To dry, drop by teaspoonful on wax paper. Turn frequently until completely dry. In Interior Alaska, drying takes about 24 hours. Store in a covered jar or airtight plastic bags. To reconstitute dried starter Crumble 2 or 3 circles of starter in 1/2 C of warm water. Let stand overnight or until bubbly. Add 1/2 C water and 1/2 C flour. Stir. Let stand for a second night or until bubbly. Use to prepare the sponge as directed in recipes. Old-timers added enough flour to their starter to shape it into a ball and then put it in a sack of flour for easy carrying. Sharing your starter To increase your supply of starter for sharing, set the sponge as directed above. In the morning, instead of preparing a sourdough recipe, remove your portion of starter as usual, then place 1/2 C portions of the starter in clean glass or pottery containers for sharing.
