Amish Friendship Bread

Amish Friendship Bread is a type of bread or cake made from a sourdough starter that is often shared in a manner similar to a chain letter. The starter is a substitute for baking yeast and can be used to make many kinds of yeast-based breads, shared with friends, or frozen for future use. The sweet, cake-like Amish Cinnamon Bread is a common bread that is made from this starter; it is a simple, stirred quickbread that includes a substantial amount of sugar and vegetable oil, with a mild cinnamon flavor. It has characteristics of both pound cake and coffee cake. The flavor of the finished product can be altered by omitting cinnamon.

A common recipe using this starter suggests using one cup (240 ml) of it to make bread, keeping one cup to start a new cycle, and giving the remaining two cups to friends. The process of sharing the starter makes it somewhat like a chain letter. One cup of starter makes one standard loaf of bread.
