Pre-heat oven to 300F degrees. Place a layer of parchment paper on a medium size cookie sheet. Set aside.
Make the popcorn according to package directions. If you make you own popcorn, do not add salt or butter but I find that microwave popcorn works just fine. Pour popped popcorn on to the cookie tray and add the pecans.
Melt the butter in the microwave for 20 seconds. Stir to smooth out. Pour over the popcorn and pecan mix, evenly. Do the same with the caramel. Sprinkle with sea salt.
Bake for 15 minutes, stop to mix (this is important, otherwise the popcorn will be unevenly coated. Bake for another 15 minutes. Remove from oven and let it cool off for 5 minutes before serving.
