Traditionally these candies are colored with saffron and served with tea, but you can also replace the saffron with various food colorings to make the candies more festive looking.
Melt the sugar in a small, heavy-bottomed saucepan over high heat. Add the vinegar, the cardamom seeds, and saffron water, and cook for 3 to 5 minutes until caramelized.
Once the syrup has caramelized, use a spoon to drip teaspoon-sized dollops of syrup on the paper, 2 in/5cm apart from each other.
