In a heavy pan, heat your oil until it's hot. Add your popcorn and cook. Since we have a gas stove, I don't have to shake the pot, but you may need to with other stove tops. When the popcorn is done remove unpopped kernels, add it to a large bowl (I use my medium stock pot), and add your pecans. Mix up the baking soda, salt, and cinnamon in a small bowl so it's ready. In a heavy pan add your maple syrup and butter. Boil this mixture until a thermometer reaches 225 degrees. Remove and quickly add your bowl with the baking soda, salt, and cinnamon and stir. Quickly pour this mixture onto your popcorn and pecans and mix until everything is well coated. Bake this on baking sheets at 225 degrees for about 40 minutes. Stir after about 20 minutes. Let it cool after baking and then enjoy.
