In a medium pan with a lid, place the duck fat and 1 kernel of unpopped corn over medium high heat. Cover.

When the popcorn pops, pour corn kernels in the pan until the bottom of the pan is covered in a single layer of kernels. Cover.

The popcorn will begin to pop. When the popping stops, shake the covered pan until more kernels pop. Do this several times until no more kernels pop. Turn off the heat.

Immediately pour the popcorn into a large bowl. Pour the melted butter over the popcorn. Then sprinkle the paprika and salt over the top. Toss or mix until the popcorn is coated.
