2teaspoonsfreshly squeezed lime juice, from about 1-2 limes
½teaspoonfinely grated lime zest
½teaspoonfreshly ground black pepper
½teaspoonred pepper flakes
Preheat the oven to 300 degrees F. Line a baking sheet with foil, silicone baking mat or parchment paper. Set aside.
Put the popped popcorn in a large, clean paper bag or a jumbo-sized ziploc bag (which is what I used). In a small bowl whisk together the butter and lime juice. In another small bowl combine the lime zest, black pepper, salt, red pepper, and cumin.
Drizzle half of the butter mixture over the popcorn, fold over or close the top of the bag, and shake until the popcorn is coated and moist. Taste. Add more of the butter mixture if you like, and give a second shake. Sprinkle most of the pepper mixture over the popcorn, fold over or close the top of the bag, and shake a few times to coat. Taste, and if you'd like more pepper flavor add the rest of it. Toss to combine.
Spread the popcorn evenly over the baking sheet and bake until the popcorn is dry, 5-7 minutes. Store in an airtight container until ready to serve (this is best served within a few hours).
