Is sherry wine the same as sherry vinegar? My recipe calls for sherry vinegar and I currently have sherry cooking wine. Can I use it?
Not really. Sherry vinegar is made from sherry wine. It is naturally more acidic in flavour. You are better off substituting another vinegar such as white wine, cider or balsamic.
If they don't taste the same, then they're not the same :)
You might be able to get a similar effect by using regular vinegar and sherry wine, in a ratio of aboutttt 3:1? Maybe some others can comment on the ratio here.
You may find that white vinegar is a bit strong though.
