When storing, remove the Grain-Fed Beef Stroganoff in its original packaging.
Remove extra liquid with a paper towel and wrap it tightly with layers of plastic film, or vacuum-seal it and freeze at 0°F (-18°C).
Keep the meat inside fridge when defrosting. Store in portion sizes to avoid thawing everything altogether and refreezing. It is strongly advised and always a good thing, to cook fresh meats at the time of purchase, to savor its freshness.
