Start by pouring the popcorn kernels into a plain brown paper bag or a microwave-safe glass bowl. If you’re using a bowl, ensure it has a lid or cover it with a glass plate to retain moisture and heat.
Next, crimp or fold the top of the bag securely. This step is crucial as it helps trap the steam, which is essential for popping the kernels. If using a bowl, simply cover it well.
Now, place the bag or bowl on its side in the microwave. This position allows the kernels to pop more evenly and prevents them from burning.
Cook on high for about 1 to 2 minutes. Keep an ear out for the popping sounds. When the popping slows down to about 5-second intervals, it’s time to stop cooking. Be careful not to overcook, as this can lead to burnt popcorn.
Once the cooking time is up, carefully remove the bag or bowl from the microwave. It will be hot, so use oven mitts if necessary. Open it with caution, as steam will escape.
Toss the popcorn with the melted butter and sprinkle with salt to taste. Give it a good shake or stir to ensure even coverage. You can adjust the butter and salt levels according to your preference.
Finally, serve the popcorn in a large bowl. You can enjoy it as is or get adventurous with additional toppings!
