⅓ cup of plain organic Greek Yogurt
Half gallon of organic milk (your choice of percent)
However much fruit of your choice you desire.
Heat the milk in a pot on the stove until it gets to around 205 F, just before it boils. Now remove milk from the stove and let it rest until it is warm to the touch.
Take the Greek Yogurt and mix it into the milk thoroughly. Once mixed in cover the mixture and place in oven with just the oven light on (do not have the heat on, this makes for a consistent temperature). Now let the mixture sit in the oven for 10 to 12 hours.
After 10 to 12 hours remove from oven and stir for consistency, the yogurt should coat a spoon. If you want a thicker consistency you can strain the yogurt through a cheesecloth. For a thinner yogurt, serve immediately after it is chilled.
Consider adding organic strawberries, blueberries, peaches or other fruit you enjoy to increase the flavor of this yogurt.
