Thaw beef tongue and remove from packaging but do not peel.
Place tongue in Instant Pot and sprinkle with 1/2 teaspoon sea salt.
Cover salted tongue with filtered water until the water covers the tongue by about 1/2 inch.
Lock lid, set Instant Pot to seal, and cook on high pressure (manual for some models) for 90 minutes. Allow pressure to naturally release (do not quick release).
Remove tongue from the water and allow to cool on a cutting board. Peel off exterior and slice meat or chop into bite-sized pieces.
