Simple syrup is easy to make and since it lasts in the fridge, one large batch is recommended. Simple Syrup is a key ingredient in thousands of drinks, and comes in many variations.

In a saucepan, combine ginger, sugar and water and bring to a boil, stirring until sugar dissolves. Remove pan from heat and cool. Strain the syrup and refrigerate syrup. Good up to one week.
Simple Syrup Variations:
Brown simple syrup: combine equal parts light or dark brown sugar with water. Bring it to a simmer and cook until the sugar has dissolved.
Honey simple syrup: use a one-to-one ratio of honey and water to make a mild flavored honey syrup or increase the honey to two parts and mix with one part water for a stronger honey flavor. For honey syrup, experiment with different honeys. Clover honey is mild and sweet while orange blossom honey might be a nice touch for cocktails that call for citrus.
Citrus flavored simple syrup: combine equal parts sugar and water then add citrus zest. Bring everything to a simmer. As the water simmers, the sugar will dissolve and the oils and flavor of the zest will seep out, making a citrus flavored simple syrup.
