Another option besides deleting is to use the "FileMaintenance". When the calculator installed it should have added a second icon called "FileMaintenance", also can be found in "All Programs->JuiceCalculator->FileMaintenance".
Launch it and open the
juice file that you want to remove recipes from on the top of the window.
On the bottom of the window you can either open another
juice file or start with a new file (the default).
Left click and drag recipes from the top window to the bottom window. Also you can right click drag and be prompted to move or copy.
On the bottom window click "Save" or "Save as" and provide a new name such as "Older recipe versions".
When you move/copy recipes, the ingredients will also copy. If moving, the ingredient(s) will only be removed from the original file if they are no longer referenced by other recipes. With this application you can also copy/move individual ingredients.
