Pour pasta and water in pot and sprinkle in some salt. Make sure all noodles are covered in water.
Close pressure cooker lid, one that isn't attached, and seal steam valve.
Push on, pressure cook, for 0 minutes. Once it beeps allow the time to go to 3 minutes natural release or 2 minutes for egg noodles.
* Be careful when steam valve is opened because some water may spirt out so place tea towel over it or adjust so valve is just slightly opened but releasing a bit slower.
Drain the water and add butter with a bit of salt and pepper to taste
