Starting the Starter, phase 2

My starter is now at the end of day five and time for the next step.

Place the starter in the refrigerator for 3 to 5 days.  Take out and feed with the following:

1/2 cup sugar
3 tablespoons instant potato flakes
1 cup warm water

Mix well and add to the starter.  Let sit on the counter all day (8-12 hours) or until bubbly.  Remove one cup to make bread and return the rest to the refrigerator for another 3 to 5 days and feed again.  If not making bread, throw away the one cup that is removed.  And the cycle begins...
