Directions
In a large saucepan, heat the milk over medium heat just until it simmer and the temperature reaches 180F. Stir occasionally.
Transfer the milk into a clean glass/heatproof airtight container. Let the milk cool to 110F. You may occasionally stir to help milk cools faster.
Add store- bought yogurt, and mix well.
Cover the container with a lid, and wrap with a clean towel to insulate the heat from the container.
Let the yogurt mixture rest (untouched) for at least 8 hours or until thickened and tangy.
Serve immediately or refrigerate the fresh yogurt for at least 2 hours before serving.
