I always have a bottle of simple syrup in my fridge for cocktails. I make mine a little richer than the usual 1:1 ratio of water to sugar. You can use 1:1 or 1.5 cups sugar to 1 cup water or even go really strong with 2 cups sugar to 1 cup water. Depends on how sweet you want it. Add the sugar and water to a sauce pan, bring to a simmer and stir well until sugar is dissolved. Transfer to a resealable jar and chill completely before using.
