Next, grab a big, sturdy pot and put it on your stove. Throw in the butter, sugar, and salt. Heat it over medium heat, and use a wooden spoon to stir until the butter melts completely. This usually takes about a minute.
Now, add your popcorn to the pot and mix it well so every piece gets coated in the melted butter mix. Put the lid on the pot and let the popcorn warm up, giving the pot a gentle shake every now and then to make sure nothing burns.
As soon as you hear the first couple of pops, lift the lid just a tad to let the steam escape. Keep shaking the pot occasionally, to keep it from burning. Keep an ear out for the popping, and when it slows down to about one pop every few seconds, take the pot off the heat. Dump all that popcorn into a large bowl.
Sprinkle your strawberry dust over the popcorn little by little. Use that wooden spoon again to give everything a good mix, making sure each piece of popcorn gets a nice coating of strawberry goodness. And there you have it – your strawberry popcorn is ready to be devoured! Serve it up right away for the ultimate tasty treat.
