Pop all of the popcorn into a large bowl - a big bowl will help when you need to stir the butter mixture to coat the popcorn evenly.

Meanwhile, in a small saucepan melt the butter with the brown sugar, smoked paprika and half of the salt. Stir with a mini whisk frequently. Allow the butter to bubble for a minute or two but keep a close eye on it because you don't want the milk solids to burn. I like to let the sugar dissolve a bit into the butter - it helps when you coat the popcorn. You will know it is ready because the sugar has blended with the butter a bit, but don't worry if there is sugar on the bottom of the pot; it doesn't need to dissolve perfectly.

Pour the butter mixture over the still warm popcorn, slowly, while stirring the popcorn with a large spoon. Keep stirring until it seems like all the pieces of popcorn have some butter on them.

Sprinkle over the remaining salt and test some to see if more salt is needed for your personal taste. Enjoy!
