Air pop the kernels. This should equal about 4 cups of popped popcorn. Take out any unpopped kernels and add the popcorn into a brown paper bag with the pecans.

In a small saucepan add the butter, sugar, syrup, and salt together. Bring to a boil. Continue to let it boil for 2 minutes while stirring constantly.

Remove from heat and stir in baking soda then stir in vanilla.

Pour the caramel over the popcorn and pecans. Close the top of the paper bag and shake together. Microwave 45 seconds then shake again. Microwave another 45 seconds and shake again.

Pour contents out into a flat baking dish and let cool. Enjoy!
