I do this, too, Millet. I can pop a cube or two of frozen lime juice into whatever I'm cooking, or even use them frozen for blended Margaritas. I freeze them up in trays, pop them out and dump the frozen cubes into a gallon freezer zip lock bag. Takes up less room in my freezer. Super handy. I also will freeze 2 cups of lemon juice into cubes, and put those 2 cups of cubes into separate zip lock bags to make a batch of lemonade (2 cups lemon juice, 4 cups water, 3/4 cup Splenda).
