Pour a little bit in the bottom of the bag, no need to measure, just remember that it takes up a lot more room after it's popped! I try to not cover the bottom completely. Fold the top down twice and put it in your microwave. The time will be different each time, but it will be around 2 minutes, maybe a TINY bit more. Just stay in the kitchen and listen to it pop.
The popcorn is way better than you would think! I used to think I needed all the extras for popcorn to taste good, but I really enjoy hot, fresh, plain popcorn. I bet you will, too! Enjoy!
