This is the easiest thing to make in just a few steps, one pan and one thermometer. Cost? About one dollar for two-three cups of Greek-style yogurt. If you purchased the same in the store, expect to pay over $3.00.
Here is what you need:
One quart of milk
2T of yogurt mixed with 2T of milk
Step One:
Bring the milk to a boil and remove it from the heat source to cool to 100 degree.
Step Two:
When the milk has achieved the right temperature, mix in the yogurt you have mixed with milk. Cover the pot with towels and let it sit in a cooler overnight or 12 hours.
Step Three:
Refrigerate and use in your favorite recipe.
Mine? Fresh berries and a teaspoon of honey.
I make a batch every week.
