Peel and cut the potatoes in to chunks and add to the instant pot.
Add the salt to the water and pour it over the potatoes.
Secure the top of the instant pot, make sure the little pointer is pointing towards sealing and add 12 minutes of time to the manual timer. Let the instant pot do it’s thing!
As soon as the time is up, release the steam manually by moving the little pointer over to venting, (do this carefully – I usually use a wooden spoon to do this so I can keep my distance.)
Remove the lid, drain the potatoes in a colander, then push them through a ricer in batches into a large mixing bowl. (If you don’t have a ricer, add them to the large mixing bowl and use a potato masher.)
Add the melted butter, half and half, salt and cracked pepper. Use your potato masher or a large wooden spoon to stir everything together, (the ricer already did all the work), then serve!
