All you need to do is the following:
Stir a 20 oz. sports drink (I like Vitamin water) and 2 cups of sugar together in a pan. Bring the mix to a boil and remove it from the heat.
After it cools, add 2 Tbsp. of regular soy sauce.
Serve immediately. Store leftovers in the refrigerator for up to three months in a covered jar or container.
