Shuck the corn, removing the husks and silk. If you bought pre-shucked corn, that's perfectly fine.
Soak the corn in a bowl of water for 5-10 minutes.
Transfer the soaked corn into a pot and fill it with water. Add approximately 1/3 teaspoon of salt. Place the pot on the stove over medium to high heat and wait until the water begins to boil.
Once the water starts boiling, turn off the heat, cover the pot with a lid, and let it sit on the same burner for 10-15 minutes. The longer it sits, closer to 15 minutes, the more tender your corn will be.
After the resting period, strain most of the water, leaving about 1 tablespoon in the pot. Add the butter and sprinkle some Pink Himalayan salt to taste over the corn. Cover the pot with the lid and let it sit for 3 minutes.
Give the pot a good shake with the lid on to distribute the butter and salt evenly over the corn. If desired, add a little more salt and shake again.
Serve and enjoy your delicious buttered corn on the cob!
