Keeping pork (any meat) in freezer

Pork sometimes is used in Chinese cooking in small amount.  However, its more economical to purchase in bigger lots and keep them in freezer. 

However, we should also freeze meat only once, that is, once thawed, we must not re-freeze it. 

Hence you may purchase 1kg chunk of pork, fillet it into ½ inches thick slices (about 100 grams each) and keep them separated in freezer plastic bags, and freeze.  ½ inches thick is good because it thawed quickly than a big chunk.  You may choose to thaw selected amount based on the recipe. 

Freeze minced pork similarly.  Put about 100 grams minced pork into plastic bag of about 4-5 inches width, remember to flatten it to thin layer, about ¼ inch depending on the size of the bag (instead of a ball).  Stack them together in a freezer box.  Again, you may choose to thaw selected amount based on the recipe, and ¼ inch thaw really fast. 

Do not freeze meat un-wrapped or covered as it will dry up the meat.
