Turkey can be brined a day ahead. Rinse well, cover and refrigerate until time to roast.
Frozen turkey tastes just as good as fresh and is easily available at any supermarket. Just remember to allow enough time for thawing, since the turkey must be completely thawed before brining. To thaw this size of whole turkey, place the turkey (in its original wrap) in a pan in the refrigerator for 2 to 3 days.
