One of the biggest uses I get out of my Instant Pot when I am not making dinner is making hard boiled eggs. I use the 5/5/5 method where I cook them for 5 minutes with a cup of water, let the pot naturally release steam for 5 minutes, then put the eggs in an ice bath for 5 minutes.
The shells fall off and the eggs are cooked beautifully! When I make them on the stove I always end up with gray rings around my yolk. No more gray rings!
