3 cups whole milk
1/4 cup powdered milk
1/3 cup yogurt
Bring milk and milk powder to 170 degrees, do not let it boil.
Cool to 108, then stir in yogurt until it's blended.
Add to yogurt maker and cook for 6-8 hours.
Cool in refrigerator.
If you're not using yogurt maker, pour mixture into 3 mason jars and put them in a crock pot on warm for 6-8 hours.
*For Greek yogurt, place a coffee filter inside a mesh colander over a bowl, then dump yogurt in. Let whey drain off for 3-4 hours, then pour into a container and seal.
