What can you substitute for cooking sherry?

Cooking sherry is low-quality sherry with salt added. There is no reason to buy cooking sherry. Purchase any inexpensive sherry and this will give you better control over the sodium content of your food. For a non alcoholic substitute try a mixture of vinegar, sugar and a dash of lemon juice OR a mixture of Apple, cranberry and Grape Juice. Orange or PineApple Juice can also be used.
