Heat a skillet over high heat. Add olive oil. When it begins swirling in the pan, add the corn and season it to taste with kosher salt. Don’t stir the corn until it begins to pop — about 45 seconds to a minute after it has been added to the pan. When it begins popping, give it a good stir and remove from the heat. That’s it. It’s done — 1 to 2 minutes total.
