Many many months ago, in Austria far away, a sourdough starter was supplied from a baker, good and qualified. The Austrian starter was dried and traveled to China where part of it mixed and grew nurtured in the presence of Chinese all purpose flour and later with Austrian Rye flour. Sometimes it sat out to grow, sometimes it sat in a refrigerator, one time even froze but it lived long and prospered and provided many a loaf of bread. Then it was dried. This happened at various times in the last few months.
