First let’s do this: I do not recommend trying coloring your kettle corn, the green coloring paste sputtered in the hot oil and is a dangerous, bad thing. I’m shocked I didn’t once again come away nursing a burn.
That said, green popcorn! This is the kettle corn recipe from Savory Sweet Life. I made it for myself one night and was so pleased with how it turned out that I decided to make a second batch for Scott when he got home. Of course I couldn’t just leave well enough, I had to endanger myself with some experimenting. It was fun to see how it turned our tongues green though.
I made half a recipe in a four quart pot and didn’t have trouble with the sugar caramelizing or the popcorn overfilling the pot.
