I plan on dry bringing my TG turkey.Will it be sucessful if the turkey is still parially frozen?
It would be better if the turkey was completely defrosted first.
No, you must allow the turkey to be fully defrosted. The salt can slow down the defrosting and not allow complete migration of the salt. It has been a rule of thumb in the dry curing business that you must allow one week per inch of the thinkness of meat to get salt into the center of the meat. Brining is quicker.
