Start by placing a trivet at the bottom of your Instant Pot bowl. I've seen people use old-school metal steamer baskets or round cooling racks. I bought the Instant Pot Silicone Trivet ($8) and am super in love. It's lightweight, and the handles don't heat up so you can swiftly remove the trivet without burning your hands.
Carefully place 1 dozen eggs on the trivet (mine were at room temperature). Fill the bottom of the Instant Pot bowl with 1 cup of water. Meanwhile in a large bowl, fix an ice bath. This will be used after the eggs cook!
