01 - Heat vegetable oil in a large pot over medium heat. Add popcorn kernels and cover with lid. Shake pot occasionally until popping slows to 2-3 seconds between pops. Remove from heat immediately and transfer popped corn to a large bowl, discarding any unpopped kernels.
02 - Combine sugar, corn syrup, water, butter, and salt in a medium saucepan. Bring mixture to a boil over medium heat, stirring constantly until sugar completely dissolves. Continue boiling for 3-4 minutes without stirring until glaze thickens slightly.
03 - Remove saucepan from heat. Stir in vanilla extract and red food coloring, adding additional drops 1 at a time until desired rosy-pink shade is achieved.
04 - Immediately pour hot pink glaze over popped popcorn. Working quickly, toss with a heat-resistant spatula or greased hands to evenly coat all kernels. Ensure thorough coverage for consistent color and flavor.
05 - Spread coated popcorn in a single layer on a baking sheet lined with parchment paper. Allow to cool completely for 15-20 minutes until glaze hardens. Break into clusters and serve.
