What to use instead of white wine in recipes? Possible Duplicate:
  What is a substitute for red or white wine in a recipe?  




I am Muslim and we do not consume alcohol in any form. I love European cuisine, but many of the recipes call for the use of white wine, or red wine or alcohol in any other form. 

So I was thinking that there must be something that can be used instead of wine in those recipes (e.g. Swiss Fondue).
A lot of the time, the major purpose of the wine is acidity. You can get this with lemon juice, tomato, or vinegar instead. Since the flavor is different, you will need to experiment by tasting, and probably use different amounts, but you should still be able to get good results. In the fondue recipe you mention, you would probably do well with a combination of lemon juice and red wine vinegar.
