Someone (I want to say RunAmok) shared this recipe here, years ago, with the title "Make this! It's delicious!" -- and it was.
It's a standby for me over the holidays. I did a search for it here but I couldn't find it, so I'm reposting.
Seriously, make this. It's delicious!
Rosemary-Caramel Popcorn Ingredients
2 tablespoons safflower oil
1/2 cup popcorn kernels
1 stick unsalted butter
1/2 cup packed light-brown sugar
2 tablespoons light corn syrup
1 tablespoon rosemary leaves
1 teaspoon gray flaked sea salt, preferably sel gris
1/4 teaspoon baking soda
Directions
Heat oil and a few popcorn kernels in a large stockpot, covered, over high heat. When they pop, add remaining popcorn kernels. Cook, shaking pot, until popped. Transfer popcorn to a large bowl.
Preheat oven to 250 degrees. Heat butter, sugar, and corn syrup in a small saucepan over high heat. Cook, stirring, until butter and sugar melt and a candy thermometer reaches 255 degrees. Remove from heat, and stir in rosemary, salt, and baking soda. Pour over popcorn; toss. Transfer to a baking sheet.
Bake, stirring occasionally, until dried, about 45 minutes. Let cool before serving. Popcorn can be stored in an airtight container at room temperature for up to 3 days.
