Things You'll Need:
- 1 quart unpasteurized milk 4 tbsp. store-bought plain yogurt with live cultures, or 1 package of yogurt starter Saucepan Candy thermometer Quart jar with lid Dishtowel Cookie sheet
-
Step 1
Pour unpasteurized milk into a saucepan and place it on a stove top.
-
Step 2
Turn the heat on medium low under the saucepan and warm the milk to 110 degrees. Use a candy thermometer to make sure you don't get the milk too hot, because heat can kill the cultures needed for making yogurt.
-
Step 3
Remove the milk from the heat and add the plain yogurt or the packaged starter, stirring to fully incorporate it into the milk.
-
Step 4
Pour the milk into a 1-qt. glass jar and wrap the jar with a dishtowel. Place the jar in the center of a cookie sheet.
-
Step 5
Preheat the oven to 200 degrees and then turn off the oven.
-
Step 6
Place the cookie sheet with the jar in the oven and close the door.
-
Step 7
Check the yogurt after 8 hours to see if the mixture has thickened. If not, run the preheat cycle of your oven again at 200 degrees and turn it off. Let the yogurt set another 3 to 4 hours.
-
Step 8
Remove the yogurt from the oven, place the lid on the jar and refrigerate.
-
Step 9
Allow the yogurt to cool completely in the refrigerator overnight or for at least 8 hours before eating.
