HOW TO MAKE THIS RAINBOW POPCORN RECIPE

STEP ONE: Pour popcorn into a large baking dish, allowing plenty of room to stir the popcorn.

STEP TWO: Combine butter, sugar, corn syrup, and sea salt in a medium saucepan, then bring to a boil over medium heat, stirring frequently.

STEP THREE: Once the mixture boils, stir in the contents of the jello packet. Return the mixture to a low boil, then let it continue to cook without stirring for 5 minutes. Keep an eye on it while it cooks. It should bubble during the full 5 minutes but not boil over.

STEP FOUR: Turn off the heat and add the baking soda. The mixture will foam up.

STEP FIVE: Pour the Jell-O mixture over the popcorn and stir it immediately to coat the popcorn evenly. 

PRO TIP: Once it starts to cool, the candy coating sets fast. Stir it quickly and evenly into the popcorn to completely coat it before the mixture starts to cool.

STEP SIX: Bake at 250°F for 55 to 60 minutes, stirring every 15 minutes. After 45 minutes, check to see if the popcorn is ready by removing a small piece and allowing it to cool for a minute or two, then check the texture to see if the coating is dry and crisp. If it is still sticky, continue cooking for 5 to 10 minutes more.

PRO TIP: If you don’t bake your popcorn long enough, it will be chewy. You can pop it back into the oven for a few more minutes if this happens.

STEP SEVEN: When popcorn is ready, remove it from the oven and immediately spread it on parchment paper to cool.

STEP EIGHT: Once it has cooled completely, break into small pieces to serve or store. Repeat the process for additional colors and flavors.

HOW TO SERVE

This sweet popcorn would be such a fun surprise on movie night. Serve up individual bowls of popcorn and a cold drink of iced tea, raspberry iced tea, sweet peach iced tea, or our southern strawberry sweet tea on the side to wash your sweet treat down.

STORAGE

ON THE COUNTER: To prevent the rainbow popcorn from getting sticky, store it in a sealed container as soon as it is cool. It does not need to be refrigerated. It will stay crisp in an airtight container for 5 to 7 days. 

IN THE FREEZER: Freezing rainbow popcorn is not recommended.

The candy coating on this colorful popcorn snack is so fun! If you make enough for a whole rainbow of flavors and colors, you can serve this delicious treat at a party and then send some home in individual Ziploc bags as cute, inexpensive party favors. Get the kids involved by letting them stir the popcorn before baking. The foamy reaction of the baking soda adds a fun food science moment to the project.
