The ingredients for this recipe are 16 cups of pre-popped popcorn (I bought the lightly salted popcorn from the grocery store but you can also air-pop 1/2 cup of popcorn kernels), 1 cup of salted butter, 1 cup of brown sugar, 1/3 cup of golden syrup or light corn syrup, 1 teaspoon of corse sea salt, 1 teaspoon of flakey sea salt (you can also just use 2 teaspoons of course salt divided) and 2 teaspoons of vanilla.
