Place the milk in a saucepan. Warm over medium heat until it reaches 180 degrees. This could take between 10-20 minutes depending on how hot your cooktop is.

Remove the sauce pan from the heat. Turn the Instant Pot on using the yogurt feature. Using the customize feature, adjust the temperature setting to 110 degrees. Set for 6 hours and start the Instant Pot (this will preheat the Instant Pot ready for yogurt making).

Let the temperature of the milk cool to 115 degrees (about 30 minutes). Remove 1/4 cup milk and place into a bowl. Stir in the yogurt until well-combined. Stir this mixture back into the milk.

Pour the milk mixture into the Instant Pot insert and secure the lid. Once the yogurt has fermented for 5 hours, remove the lid and examine the texture. If a thicker consistency is desired, continue to let the yogurt ferment. Be sure to restart the Instant Pot and set for the desired time at 110 degrees.

Remove the insert and place the yogurt into an air tight container. Store in the fridge for at least 6 hours.

Remove and strain for desired consistency. Whisk until smooth.
