Instructions
- Step 1: Pop 1/2 cup popcorn kernels using an air popper or stovetop method until you have about 12 cups of popped popcorn. Transfer to a large mixing bowl, removing any un-popped kernels.
- Step 2: In a medium saucepan over medium heat, melt 4 tbsp unsalted butter. Stir in 1/2 cup granulated sugar and 1/4 cup light corn syrup. Bring to a boil and cook without stirring for 4-5 minutes until the syrup reaches 250°F on a candy thermometer (hard ball stage).
- Step 3: Remove the saucepan from heat and stir in 1 tsp pure vanilla extract and 1/4 tsp baking soda until the mixture is foamy and light.
- Step 4: Quickly pour the hot vanilla syrup over the popcorn and gently fold with a spatula to coat all the kernels evenly. Sprinkle 1/2 tsp sea salt flakes over the coated popcorn and mix lightly.
- Step 5: Spread the coated popcorn onto a parchment-lined baking sheet and let it cool completely for 30 minutes until the clusters harden. Break into bite-sized clusters and serve.
