Pressure cooker on instant pot for a 2-2.5 lbs tongue for 1.25-1.5hrs for more firm texture or 2-2.15hrs for braised style. Let pressure come out naturally over an hour. I typically like to just use aromatics and water. Then when rested and cool I will peel and slice or pick whatever you prefer. Then I will add it to a sauce that I make during the cooking time of the tongue. Like mole, salsa negro, salsa verde, Hungarian pepper sauce, etc.
