Homemade Plain Whole Milk Yogurt In The Instant Pot Recipes

Steps:

• Pour the milk in a 6-quart Instant Pot® and put on yogurt setting. Press the adjust setting to boil (see Cook's Note). Follow the manufacturer's guide for locking the lid and preparing to cook. After the boil cycle is complete follow the manufacturer's guide for quick release and wait until the quick release cycle is complete. Be careful of any remaining steam and unlock and remove the lid.
• Stir the milk and check the temperature using an instant-read thermometer. The milk must reach a temperature of at least 180 degrees F. If the milk is not yet hot enough, repeat the boil cycle until the milk comes up to the correct temperature.
• Remove the pot insert and allow the milk to cool until it reaches a temperature of 110 to 115 degrees F. (To speed up this process, place pot in an ice water bath and stir, being careful not to get any water into the milk.) Place 1/2 cup of the milk in a small bowl and stir in the store-bought yogurt until combined. Stir the yogurt mixture back into the milk mixture in the pot.
• Follow the manufacturer's guide for locking the lid and preparing to cook. Put on the yogurt setting and set the time for 9 to 12 hours (9 for a looser, milder yogurt and 12 for a thicker, tarter yogurt).
• Remove the lid (there will be no pressure, so no pressure release is required). Carefully remove the yogurt and transfer to resealable containers.
• Refrigerate until completely chilled and set, about 4 hours.

Steps:

• Place the milk in the inner pot. Close and lock the lid. Set the valve to Sealing. Press the Yogurt button and then press the Yogurt or Adjust button until the display reads "Boil."
• Allow about 30 minutes for the program to finish. When it has finished, press Cancel until the display reads "Off." Use oven mitts to remove the inner pot (be careful-it's hot!) and place it on a trivet or other heat-resistant surface. Allow the milk to cool, stirring occasionally, until the temperature drops to 110°F as measured on an instant-read thermometer, about 1 hour. (If you do not have a thermometer, use a small spoon to drip a few drops of the milk on the inside of your wrist. It should feel just above body temperature-very slightly warm but not hot. Err on the side of too cool, since too much heat will kill the necessary bacteria in the yogurt in the next step.)
• Add the yogurt to the inner pot and stir thoroughly.
• Return the inner pot to the Instant Pot. Press the Yogurt button and use the Yogurt or Adjust button to select the middle temperature ("Normal"). Use the − or + button to set the time to 8 hours. Close and lock the lid. Set the valve to Sealing.
• When the cycle ends, press Cancel and remove the lid. Stir the yogurt and then use a large spoon to scoop it into a container with a lid or single-serving containers with lids. Place the covered container(s) in the refrigerator to cool, about 3 hours, before serving.
• Whole Milk Yogurt will keep, in an airtight container in the refrigerator, for up to 2 weeks.
