If It is the day before Thanksgiving and I need to cook the turkey in the next 24 to 30 hours, is it worth trying a dry brine?
Yes - if you do the brine now and you cook the turkey tomorrow morning it will still have more than 12 hours of brining
Yes -- even just a few hours of dry brining is helpful. So if you can, brine it now!
Sure, I would do it. But start it right this second! :)
