I prefer the 5-5-5 method in the Instant Pot. To follow this method, place 1 cup of water in the insert. Place the wire insert in the water, and place the eggs atop it. Set the Instant Pot for 5 minutes and let it come to pressure. This takes more than 5 minutes, keep in mind.
While this is going on prepare the pickling mixture by bringing the apple cider vinegar, 5 ounces of water, white sugar, turmeric, mustard seeds and powder, coriander seeds, and the black peppercorns in the ingredients list to a gentle simmer for 2 minutes.
Remove from the heat and pour the mixture into a container large enough to hold the liquid and all of the eggs. Let cool completely.
Once the Instant Pot's 5 minute timer goes off, set a timer of your own for 5 minutes, let the eggs rest in the pressurized Instant Pot for 5 minutes.
Then release the valve and use tongs to put the eggs in a waiting large bowl of ice and cold water for 5 minutes.
After 5 minutes in the cold water, dry the eggs and peel them. Place the eggs in the cooled turmeric pickling liquid and cover with a lid. Place in the fridge for UP to 23 hours and no more than that. I like to make the eggs and leave them in the fridge overnight.
