Certain turkeys are pre-brined, so don't waste your time: check first. Kosher turkeys and some commercial brands like Butterball are "pre-basted" or brined. The ingredients should list seven percent of an added solution (water or vinegar). But be careful: pre-brining can mask other added junk like preservatives, so if you want to go au natural, buy a fresh one without additives and brine it yourself.
To brine your turkey, soak the bird in some salty, sugary, (insert spice here)-flavored water overnight. Dry it off, rub on some butter or oil, and throw her in the oven. Sure, brining requires some time, but when else will you commit such time for brining? At least try it if you don't have a stance.
