• Remove the yogurt culture and bring it to room temperature. (Not necessary, but I prefer doing this)

Boiling and cooling milk

• In a heavy bottom pot, add the milk.
  1 Ltr Milk
  
• Boil the milk and switch it off.
  
• Let the milk come to a lukewarm temperature. (The milk should be warm to touch but not hot. I.e. when you dip your finger you should be able to hold it. If you are using a thermometer, the temperature of the milk is around 39 Deg C / 102.2 Deg F.)

Adding the yogurt Culture

• Now in a clean pot add the yogurt culture and around ½ cup milk and mix.
  3 tablespoon Yogurt starter culture
• One can add the yogurt culture directly too in the same pot as the milk is added. I do it separately as the culture then mixes properly.

Frothing milk (Optional - But helps in setting thick yogurt)

• Pour the milk from one pot to another from a little height.
• Continue the above step 3-4 times. This helps in breaking down any cream or fat formed in the milk. This also helps in the even distribution of the yogurt culture.
• Frothing helps to set the yogurt thick and with that perfect creamy texture.
• Add milk in individual jars or in a bowl.
  

Setting the yogurt in Instant Pot

• Place a trivet in the bottom of the inner of your Instant Pot.
• Add 1 cup water.
  1 Cup Water
  
• Place the pot inside and lightly cover with a plate. (One can even leave it uncovered)
• If using jars, just lightly top the lid. Do not close it tight. (One can even leave it open)
  
• Now close the Instant pot, and switch off the Instant Pot to Yogurt Mode.
• This automatically sets to 8 hours. ( I set mine for 6 hours and it works).
• Once the timer beeps and you when instant pot reads "yogt", yogurt is ready.
  
• You can enjoy this as is or for best results keep it refrigerated for 2-3 hours.

Instant Pot Yogurt without Yogurt Button

• Follow the same procedure for boiling, cooling, adding of yogurt culture and frothing of milk
• Place a rack in the bottom of the inner of your Instant Pot.
• Add 2 Cups boiling water.
• It will work without boiling water too, as I have tried that, but just to be on the safer side.
• Place the pot inside and lightly cover with a plate. (One can even leave it uncovered)
• If using jars, just lightly top the lid. Do not close it tight. (One can even leave it open)
• Immediately close the instant pot Lid and leave it untouched for 12 hours.
  
• After 12 hours open the lid. Your yogurt should be set.

Greek Style yogurt

• Keep a strainer on top of a pot. One can add a muslin cloth to this, or can directly add yogurt in the strainer if you have a fine mesh in the strainer.
• Add the yogurt to this. You should have the strainer on top of the pot so that the water gets collected down.
• Water will be collected down in the pot and you would be left with thick yogurt in the strainer.
• The leftover water can be enjoyed as is or with some salt and cumin powder to make cooling buttermilk.
• Keep this refrigerated for 5-6 hours.
