Simple syrup is equal parts sugar and water, simmered until the sugar dissolves. Simple as that! It is an indispensible ingredient when it comes to sweetening cold drinks, like iced coffee, iced tea, and cocktails. Since the sugar is already dissolved in water, it is easily and evenly mixed into the beverage of your choice. You’re left with a seamless, satisfying beverage, without the accumulation of sugar crystals in the bottom of your glass.
