The NY TImes just posted a recipe for ginger ale (http://www.nytimes.com/2009/05/20/din...). It looks awesome and I look forward to trying it especially in the hot summer months. The recipe suggests making a ginger syrup if making a large quantity by dissolving 3/4c sugar in 1 c ginger juice. Does anyone know how long this syrup would last in the fridge? Can it be frozen in an ice cube tray?
