Amish Friendship Bread Starter

In a small bowl, dissolve yeast in water. Let stand 10 minutes. In a 2 quart container glass, plastic or ceramic container, combine 1 cup flour and 1 cup sugar. Mix thoroughly or flour will lump when milk is added. Slowly stir in 1 cup milk and dissolved yeast mixture. Cover loosely and let stand until bubbly. Consider this day 1 of the 10 day cycle. Leave loosely covered at room temperature. On days 2 through 4; stir starter with a spoon. Day 5; stir in 1 cup flour, 1 cup sugar and 1 cup milk. Days 6 through 9; stir only. Day 10; stir in 1 cup flour, 1 cup sugar and 1 cup milk. Remove 1 cup to make your first bread, give 2 cups to friends along with this recipe, and your favorite Amish Bread recipe. Store the remaining 1 cup starter in a container in the refrigerator, or begin the 10 day process over again (beginning with step 2).
