Good Cooking Wine?

[The Poet]

You have gotten all the good advise you need already, brother. I'll just add that so-called "cooking wine" is deliberately salty, in order to dissuade people from drinking it. Here in our store we keep a few bottles of cheap ($5.00) sherry and marsala for cooking, but they can also be drunk . . . as can thereby the cook.

Look at it this way: You can always add salt to a dish, but it's harder to take it out.
