There are lots of ways to make yogurt, but this is how I have been doing it with good results:
- First, I warm 1/2 gallon of milk to 180 degrees.
- Once the milk has reached 180 degrees, I take it off the stove and cool it to 110 degrees. I do this by filling the sink with a little cold water and put the pan in the water, careful to not get any water in the milk.
- Next I add the starter. The first time I used store bought plain yogurt and added 1 cup to the 1/2 gallon of milk. This time I just used some left over yogurt from my first batch.
- Mix well and pour into a very clean 1/2 gallon jar or smaller jars.
- Now this is where the magic happens! With the milk and starter well mixed, I place the jar in an insulated cooler with a heating pad wrapped around it. I turn the heating pad to medium heat and zip the top of the insulated cooler. I leave the lid off the jar (I don't know if that matters or not, but I don't want extra moisure in there). I then let this sit and incubate for 6-8 hours.
And there we have it-yogurt!
