One of the biggest reasons I love my pressure cooker is for Homemade Yogurt.

It was one of the first recipes I mastered and I make it every week.

But a lot of people have been asking how to make Cold Start Yogurt, and I am here to say, that Instant Pot Cold Start Yogurt is so much easier than my original Instant Pot Yogurt Recipe.

Cold Start Yogurt

It could not be easier to make yogurt using cold start yogurt, and it is nearly IMPOSSIBLE to mess up--the same can not be said about my traditional Instant Pot Yogurt.

There are no thermometers needed, no boiling of milk, and no wondering if your milk didn't reach the right temperature to achieve perfect yogurt. Plus cold start yogurt comes out thick, just like Greek yogurt--no need for straining!

Just two simple ingredients and a pressure cooker are all that is needed for this cold start yogurt.

Ingredients for Cold Start Yogurt

• Ultra Pasteurized Milk or Ultra-Filtered Milk
• 2 tablespoons plain yogurt with active cultures or a yogurt starter

Ultra Filtered or Ultra Pasteurized?

Cold start yogurt works using milk that is ultra-pasteurized. That said, for the creamiest, thickest yogurt, ultra-filtered milk works best.

Ultra-Filtered milk is still pasteurized, but it also goes through a special filtration process.  The result is ultra-filtered milk with 50% more protein, 30% more calcium and half the sugar of regular milk and lactose free. Which yields a yogurt that is creamier and thicker. It also is higher in protein and calcium and lower in sugar--perfect for anyone watching their sugars.

You can look for a brand, like Fairlife brand for ultra-filtered milk.

How To Make Cold Start Yogurt

Step One: Clean your Instant Pot

• Be sure your pressure cooker is clean and you use a clean inner ring when making yogurt--no one wants yogurt tasting like Instant Pot Chili!
• I wipe my inner pot down with vinegar and then rinse well and dry.
• I also recommend a separate sealing ring to use for yogurt--not necessary but it does help!

Step Two: Add Milk and Starter to Pressure Cooker

• Whisk 1 cup of the milk with the starter until well combined.
• Pour remaining milk into inner pot of pressure cooker.
• Whisk in starter mixture.

Step Three: Incubate Yogurt

• Place lid on pressure cooker.
• Hit "Yogurt" and it should read 8:00. Be sure NORMAL is lit up. If LOW is let up, you must change to normal heat for incubation to occur, by hitting yogurt again until normal is lit up. 
• Let it begin to incubate.

Step Four: Refrigerate Yogurt

• After 8 hours, remove inner pot from pressure cooker.
• Cover with plastic wrap and refrigerate for another 8 hours.
• Place yogurt in glass jars to store in refrigerator.

Tips for Making Cold Start Yogurt

• There is NO substitution for ultra-pasteurized milk. If you do not use ultra-pasteurized milk, you need to follow these instructions for Instant Pot Yogurt. Most Organic Milks are Ultra-Pasteurized as well--but be sure it is labeled "ultra-pasteurized"
• Use any percentage of fat milk you like for this cold start yogurt, the higher the fat percentage the creamier the yogurt. I prefer 2% Ultra Pasteurized Milk.
• You can cut this recipe in half, or if you have an 8-quart pressure cooker, you can also double this recipe for homemade yogurt.
• For homemade yogurt, you must use either use a yogurt starter or plain yogurt with active live cultures.  I like to use plain Greek yogurt--Chobani or the store brand.
• Feel free to sweeten yogurt with vanilla extract, honey, maple syrup, or fruit AFTER incubating.
• A huge tip for making yogurt in the future is to FREEZE your starter immediately after fresh yogurt is made. I recommend using an ice cube tray. Each ice cube holds 1 tablespoon of yogurt so you will know exactly how much yogurt to defrost when making a new yogurt batch. Just be sure to thaw your yogurt cubes in the fridge to not alter the cultures in the yogurt.
• If you would like tangier yogurt, set the incubation period to 10 hours instead of 8 hours.
• Homemade yogurt should last for up to 10-14 days in your refrigerator.
