In a small bowl, dissolve yeast in water. Let stand 10 minutes. In a 2 quart container glass, 1 gallon plastic freezer bag 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, and if using Gallon bag, express the air and seal the bag ,stirring can be done by simply squishing the bag a few times*
On days 2 thru 4; stir starter with a spoon*. Day 5; stir in 1 cup flour, 1 cup sugar and 1 cup milk. Days 6 thru 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). Can also give away three and start from scratch but it won't develope the richness that aged starter gives to baked goods.
