Stir all of the ingredients in a large glass bowl (no metal bowls allowed as this mixture will absorb the taste of the metal). Cover the bowl with a cloth and stir once a day for 4 days. The mixture will bubble and smell somewhat. Next cover and refrigerate. Keep replacing the amount used by replenishing ingredients in a like quantity, only do not add any more yeast. Important: If starter turns to an orange or purple color discard at once and begin again.
