Make a batch and store it in a squeeze bottle or small jar -- it keeps forever in your fridge. You can also use this soluble sweetener when a recipe calls for agave syrup.
In a small saucepan over medium heat, combine 2 cups each sugar and water. Bring to a simmer, stirring until the sugar dissolves. Simmer for 1 minute, then pour into a heatproof glass jar. Let cool, then refrigerate before using. Makes 3 cups.
