   Heat milk until it reaches 100F (38C) on a thermometer. Remove from heat and stir in yogurt. Port mixture into a clean plastic container, cover tightly and let stand in a warm place for 18 to 24 hours. Be sure to punch a small hole in container lid to allow gases to escape. Mixture should resemble the consistency of yogurt.
