Making yogurt is a simple way to feed the kids healthy inexpensively. No additives or preservatives.
All you need is a gallon of milk and half a cup of plain yogurt.
Bring the milk to 180 degrees, then remove from heat and allow the heat drop to 110. Stir in 1/2c plain yogurt. Pour mixture into 4 mason jars. Place in a large picnic cooler. Use the hottest tap water you have to fill up to the neck of the jars, close the lid overnight. In the morning you have a gallon of plain yogurt for less then $4.
Sweeten to taste, I usually add wild black raspberries that we picked and froze last summer.
For detailed instructions please see a wonderful blog site, I attended her cheese making class. She is quite an inspiration!
