Your plan should be fine . I was just stating some things to be aware of . I have had them go south after opening them . Most of those were close to date when they were frozen , so anytime after thawed creeps up on being past date .
Just my experience that once they hit the air the clock starts ticking ,,, sometimes .
I just did a brisket that was two years old . Frozen original vac . I got it out to grind , but after thawing it started to brown up . So I threw the point in the crock pot and cured the flat .
Don't let me cause you concern . I was just sharing my experience of doing this . I've almost got the older stuff cleared out .
