Pressure Cooker Instructions: If you'd like to cook both the potatoes and the eggs at at the same time in the pressure cooker, place 1 1/2 cups water in your pressure cooker. Place potatoes in a steamer basket if you have one, and then nestle the eggs on top of them. Cook on high pressure for 4 minutes and then let rest for 5 minutes before releasing pressure. Place eggs in ice bath to stop cooking and spread out potatoes on a baking sheet to cool and get rid of extra moisture. Let potatoes cool to room temp or chill before mixing up salad.
