Quote: I go to the section of the grocery store that has vinegar, salad dressing, etc. There they have several types of cooking wine to choose from. I believe there are differences from regular wine, but I don't know the specifics of this.
The big one that I know of is that "cooking" wine from the grocery store is salted so it's not drinkable (that's why they can sell it at the grocery store and not the liquor store). Personally, I'd go to the liquor store and buy a bottle of cheap-but-not-sketchy wine and use it in the recipe, then you can freeze the rest in ice cube trays to use in other recipes later on....
