Sugar - 1 cup
Water - 1/4 cup
Put sugar and water in a pot and heat it on medium flame. DO NOT STIR. Stir only initially until all the sugar dissolves. After that, STOP. Stirring can crystallize the sugar. After sometime, the solution starts to change color. Once it starts to change color, it changes rather quickly. So keep an eye. It can burn really quickly. To check the color I take a white bowl/plate and start putting droplets of syrup on it. Once it reaches a deep amber color, it is done.
After it is done, you should act fast, as it can solidify very quickly.
