Drain half the water from your can of corn and place the corn in a 9" skillet. If you are making a larger batch, use any size pan or pot that will hold the corn without spilling.
Add the butter and salt and bring the skillet to a gentle simmer over medium high heat.
Reduce the heat to medium and stir occasionally so the corn doesn't burn. Cook until the liquid is almost totally gone and just a couple of tablespoons remain in the bottom.
Serve warm.
Notes
Note 1: If your corn is unsalted, consider using 1/2 teaspoon salt. Add half and taste it first, then add the rest if needed. To make this dish for more than 2 people, simply multiply the ingredients.
