Carameloffee Corn is a delicous caramel popcorn made with Coffee Syrup, so it has an extra delicious zing.
(Recipe adapted from "How to Make the Best Caramel Popcorn" on thekitchn.com)
Arrange two oven racks in the top and bottom third of the oven and preheat oven to 250°F. Line baking sheets with parchment or silicone mats.
Make caramel sauce. Combine Coffee Syrup and butter in a medium size pot over med-hi heat. Boil and - monitoring with a candy thermometer - bring temp to at least 250°F (up to 300°F. )
Add vanilla, salt, baking soda. Remove pot from heat, add vanilla, salt, and baking soda, and stir until combined. The mixture will bubble up significantly. Continue stirring until you get a thick, glossy sauce.
Combine caramel sauce and popcorn. Slowly pour caramel sauce over popcorn while stirring the popcorn (it helps if you have a partner for this step — one person pouring while the other stirs the popcorn). Continue stirring the sauce into the popcorn until all the kernels are coated.
Bake the caramel popcorn. Divide the popcorn between two baking sheets, spreading it out into an even layer. It's ok if the popcorn clumps together. Bake for one hour, stirring every 15 minutes and breaking up any clumps.
Let cool completely. Let the popcorn cool completely on the baking sheets. Break it up and serve immediately or store in an airtight container for up to a week.
