Cook your popcorn kernels your preferred way. If using a silicone popcorn bowl, cook kernels in the microwave with the lid on for about 3 minutes on high, or until popping slows to 8 seconds between pops.
While popcorn is cooling slightly, melt butter in the microwave (around 45 seconds to 1 minute).
Pour popcorn into a mixing bowl. Drizzle a third of the butter over popcorn, then sprinkle with salt to taste. Stir with a spatula or wooden spoon. Repeat two more times with the remaining butter and your preferred amount of salt. Enjoy!
