Leeching a potato involves boiling the peeled and cut potatoes (and other high potassium root vegetables) twice. Simply soaking in cool water then changing the water to boil, does not leech out a significant portion of the potassium. Using large amounts of water and boiling initially for 10 minutes, then changing the water and cooking the remainder of the way will leech out some potassium. This method is one to consider for those that are on a potassium restriction. If no potassium restriction, this method likely isn’t needed.
What does it mean to leach a potato and does it bring down the potassium?
