This product is SO fantastic and has been a huge hit in my house. Seriously, if you are still eating microwave popcorn out of a bag, it's time to head to your local Target and pick one of these up.
On here the nordicware website it is more, but it is on special right now at Target for $8.99 I found it in the same aisle as the popcorn.
This isn't a separate appliance, it's simply a specialized bowl and lid that go in your microwave. Add 1/3 cup popcorn, and set the time like you normally do for your bag of popcorn. You DON'T need to add any oil. After it's done popping add your favorite seasonings, put the lid back on, shake, then enjoy!
My favorite seasoning is 2 tbsp butter + a couple pinches of salt. Salt goes a LONG way, so don't add too much!
The bowl is so easy to clean, it is top rack microwave safe. Also, you can use it as a serving bowl! So if you are using a bowl to put your bagged popcorn in, you really don't have much more to wash. Fresh popcorn tastes so much better, and you can make it much healthier and control the ingredients that go in to it.
