Creating Red Candy-Coated Popcorn is straightforward if you follow these easy steps:

1. Pop Popcorn: Start by popping your popcorn using an air popper or via stove-top methods. Place the popped popcorn in a large mixing bowl and set aside.
2. Prepare Baking Sheet: Line a large baking sheet with parchment paper or a silicone mat.
3. Make Candy Coating: In a saucepan over medium heat, combine sugar, butter, corn syrup, and salt. Stir until melted and bring to a boil.
4. Simmer Mixture: Allow the mixture to boil without stirring for about 4-5 minutes, until it reaches a soft ball stage (about 240°F/115°C).
5. Add Color and Flavor: Remove from heat and carefully stir in baking soda, vanilla extract, and red food coloring. The mixture will bubble up; this is normal.
6. Coat Popcorn: Pour the candy mixture over the popped popcorn in the bowl. Gently toss to coat the popcorn evenly. Be careful, as the mixture will be hot.
7. Spread on Baking Sheet: Transfer the coated popcorn to the lined baking sheet. Spread it out as evenly as possible.
8. Cool: Allow the popcorn to cool completely. This will help it set and become crunchy.
9. Break Apart: Once cooled, break up any clumps to separate the popcorn pieces.
10. Add Toppings: If desired, sprinkle additional toppings like sprinkles or nuts over the popcorn.
