1-Start: Start by preheating your oven to 250°F (120°C) and popping your popcorn fresh it makes all the difference for that great texture. Measure out 10 to 11 cups of air-popped popcorn and place it in a big bowl, picking out any unpopped kernels to avoid surprises. This first step sets the stage for a smooth process.

2-Next: In a saucepan, melt 1/2 cup of unsalted butter over medium heat, then stir in 1 cup of packed light brown sugar, 1/4 cup light corn syrup, and 1/2 teaspoon salt. Keep stirring until it boils, which helps blend the flavors just right. Let it boil for a few minutes to get that perfect caramel consistency.

3-Once it reaches the right stage: Remove from heat and mix in 1/2 teaspoon baking soda and 1/8 teaspoon cream of tartar; it will bubble up, so be careful. Pour this warm caramel over your popcorn and stir gently to coat every piece evenly. For the best results, spread it on baking sheets and pop it in the oven.

4-Baking and Cooling Tips: Bake the coated popcorn for about 45 minutes, stirring every 15 minutes to ensure even crispiness. This part is key to getting that golden crunch without any soft spots. After baking, let it cool completely on the sheets before breaking it apart.
