Set up a steamer. Fill with one inch of water and place over medium-high heat. Refer to the lessons on Steaming for more information, if necessary.
For even cooking, make sure to buy potatoes that are all relatively the same size. Wash the potatoes and place into the steaming basket. Sprinkle with a pinch of sea salt. Once the water is simmering, place the basket over the pot and cover with a lid. Steam until tender and cooked through, about 20 minutes or so.
