I have used Mastercook's recipe copier for many years and have found it to be extremely stable and useful. Now that it is an add-on to web browsers it is even more useful providing smoother to use than it was before. It is quite easy to use and produces searchable recipes in the Mastercook database. I have not found any other product that is as useful and well thought out than the Mastercook add-on.

I love this app. I use it daily. Can't have MasterCook without it :-)
