I have an Instant Pot Duo, so why would I create recipe to make yogurt in the Lux model? I have a ton of yogurt recipes on my blog and whenever I share any of the recipes, the question about making yogurt in a Lux Instant Pot always comes up – so being the ever curious person that I am, I wanted to figure out a way to do it.
The Keep Warm function is on every model and usually keeps food at around 135°F-165°F which is too hot to make yogurt – the ideal temperature for making yogurt is 110°F-115°F, but yogurt will still culture at temps as low as 100°F. So I placed the trivet in the pot, pressed the Keep Warm button and placed a jar that had water that I heated up to 115°F onto the trivet – I left the lid off of the Instant Pot because I knew that would be too hot. I checked the temperature every few hours and it stayed steady around 100°F-102°F. I tried putting a towel over the top of the Instant Pot, but the water reached 125°F which is too hot for yogurt.
After seeing that it could keep a jar of liquid at around 100°F I mixed some yogurt starter with milk and tested this technique. I press the Keep Warm button and set it for 11 hours – when the time was up I refrigerated it overnight and the next day I had delicious yogurt! It was thick enough that it doesn’t drip out when the jar it’s placed on it’s side and the yogurt was nice and creamy. Since this is made with the Instant Pot lid off, the room temperature can effect the temperature of the milk, so if you try this method, keep the Instant Pot away from any cold or drafty areas. Glass yogurt jars or 4oz Mason jars work great for this technique, if you have a cake pan that fits into the Instant Pot with the trivet you could use that as well. You can also invest in a yogurt maker instead, they are quite cheap and come with glass jars (link to one here).
Tips on making thicker yogurt without straining:
*Use Whole Milk, low fat milk will produce thinner yogurt
*If you’re doing the boil method, hold the temp at 180°F – 190°F for 20 minutes – this helps evaporate the milk which will make thicker yogurt
*Blend dry milk powder into your milk – adding more protein will make your yogurt thicker
*Use sweetened condensed milk as your sweetener, works by adding more protein to your milk
*Use Fairlife brand milk, it’s Ultra-Pasteurized and Ultra-Filtered and has a much higher protein content than regular milk.
