==Controlling the starter cycle==
<!-- Wikipedia is not a cookbook or a how-to manual.  Please do not add your favorite recipes to this article. -->
A common cycle is based on the addition of one cup each of sugar, flour, and milk every five days, with bread baked and extra starter shared every tenth day.   The ten-day cycle produces five cups of starter, which must be either used to bake bread, given away, or used to start a new cycle.  A common suggestion is to bake one loaf of bread, give away three cups of starter, and to save the remaining one for the next cycle.

It is not necessary to wait the canonical ten days before using one cup of starter:  a cup of starter can be used as a yeast substitute at any point.  However, using starter on earlier days will result in a smaller quantity of starter at the end of the cycle.  To avoid running out of starter, it is normal to feed the starter (add milk, sugar, and flour) before removing a cup for use, and most recipes assume that starter is always fed immediately before being removed.  A five-day baking cycle feeds the starter every fifth day and uses the resulting mixture on that day to bake one or two loaves of bread (one cup per loaf).  The remaining starter is reserved to begin the next five-day fermentation cycle.

Despite common instructions to the contrary, the starter can be frozen for later use,<ref name="titlenewsminer.com • Amish Friendship Bread comes with a commitment"/> and the cycle begun anew after thawing.  The cycle can also be slowed to about half the normal fermentation rate by refrigerating the starter instead of allowing it to ferment at [[room temperature]].  Refrigeration is usually recommended if a few days' delay is desired.
