This is for a 100 year old Alaskan sourdough starter (wheat). The starter also comes with a maintenance guide and some recipes. Recipes include instructions for sourdough bread, french bread, cheese biscuits, pancakes, oatmeal cookies, peanut butter cookies, cornbread, and cinnamon rolls. This starter is a centry old and will continue to thrieve for another centry if properly used. I make sourdough bread and pancakes every week and this is one of the best things that I came across so far in Alaska. Questions are always welcome.
