01 - Heat vegetable oil in a large pot over medium heat. Add popcorn kernels, cover with lid, and shake pot occasionally until popping slows significantly. Remove from heat and transfer popped popcorn to a large mixing bowl, carefully discarding any unpopped kernels.
02 - In a medium saucepan over medium heat, combine granulated sugar, light corn syrup, water, unsalted butter, and salt. Stir continuously until sugar completely dissolves, then bring mixture to a boil. Continue boiling for 3-4 minutes without stirring until syrup slightly thickens.
03 - Remove saucepan from heat immediately. Stir in vanilla extract and red food coloring, adding additional drops one at a time to achieve desired rosy pink shade.
04 - Working quickly, pour hot pink glaze over prepared popcorn. Toss vigorously with a heat-resistant spatula or greased hands to ensure every kernel receives an even coating of the candy glaze.
05 - Spread coated popcorn in a single layer on a baking sheet lined with parchment paper. Allow to cool completely at room temperature until glaze hardens. Break into clusters and serve.
