Rinse the sorghum with cool water.
Add the rinsed sorghum to the Instant Pot with water and salt. Close the lid with vent in sealing position. Cook on high pressure for 30 minutes.
Let the pressure release naturally, then open the lid.
Drain any excess liquid by transferring the cooked sorghum to a strainer. Fluff with a fork and season to taste. Serve hot or cold, in soups and salads, or as a side dish.
