Wash and cut up the rhubarb and place in a steamer basket.
Put one cup of water in the bottom of the liner of the Instant Pot. Place the steamer basket in the pot, lock on the lid, and set the manual/pressure cook timer to 4 minutes. Make sure your toggle is set to sealing.
When the cooking cycle is done, allow for a five to ten minute natural pressure release. (NPR) Remove the steamer basket and spoon the rhubarb into a bowl. Add the other ingredients and stir well. Taste and adjust the seasoning if needed. Place in a mason jar and store in the refrigerator.
Take the rhubarb juice from the bottom of the liner and also place in a small mason jar. This excellent juice can be used for cocktails, or rhubarb lemonade, or, just a few sips straight is good as a remedy for constipation!
