...only because I can't seem to find an answer to this online anywhere (but maybe I'm not using the right keywords). I'm trying to find a nice brine recipe for turkey. So far, everything I've seen says that ice is part of the recipe. However, my car is on the fritz and I can't get anywhere to buy ice this AM. Is the ice "necessary"? If so, can I substitute cold water for it, and how much water would I substitute?
