Epicurious.com. Dry Brining by Rick Rodgers How does this dry salt rub work? The salt draws a tiny bit of moisture from the bird and opens the skin pores. This moisture mingles with the salt and works its way into the turkey muscles, seasoning the bird throughout through osmosis. It is much less awkward than brining with gallons of salt water! prep time is refrigeration and cooking time varies greatly depending of your preferred method, i just threw in 8 hours, please disreguard.
