As with most meat, the safest way to thaw beef is in the refrigerator. Small cuts of beef can take up to 24 hours, while larger slabs can take a few days. If you’re in a pinch, frozen beef can be thawed in a bowl or container of lukewarm water. Place the bowl or container in the sink and leave under a running faucet. Never allow raw beef to thaw or sit on a counter or cutting board. Since it takes longer to thaw than most meats, it is more susceptible to bacteria growth.
In order to effectively freeze beef, you’ll want to limit its exposure to air. This not only prevents the production of freezer burn, but also extends its shelf life to three months or longer. The best way to package beef is to wrap it tightly in freezer paper or plastic wrap. You should then wrap the meat in a layer of aluminum foil or place it in a plastic bag.
For ground beef, keep refrigerated and use within one to two days. It can stay in its original container if the packaging hasn’t been opened. Steaks follow the same protocol, but can last a bit longer at three to five days. It’s actually best to allow a little airflow with stored meat, as tightly-adhered plastic like Saran wrap can make meat sweat and, as a result, less tender. Meat can be transferred to plastic containers, but should be covered loosely.
Never refrigerate raw meat if it’s been sitting out beyond two hours.

Why Do We Celebrate Christmas on Dec. 25?
There are several reasons Christmas is celebrated on Dec. 25. The date is nine months after March 25, a day recognized by Christians as Annunciation. It was the day Mary was told she would was having a baby. The nine months that follow are an approximation of Jesus’ birth. Dec. 25 also coincides with pagan Winter Solstice celebrations like Saturnalia' and Dies Natalis Solis Invicti. Since they were historically celebrated around that time of year there was precedent for holiday festivities during this time of year.

How Can We Celebrate Christmas?
Christmas is traditionally celebrated in many ways and celebrations vary across cultures. In the days leading up to Christmas, people usually put up special decorations including colorful lights and evergreen trees. Gifts are often placed under the tree and exchanged on Christmas day among loved ones. Large meals are also typically served as part of the celebration as well.
Pork fares best in the freezer if packaged with freezer-friendly materials like waxed paper, aluminum foil, or heavy-duty plastic bags.
Wrap any meat tightly so that air does not escape and freeze at 0°F. Generally, fresh cuts of pork can last up to six months, while ground pork can last up to three.
Pork is easiest to thaw when placed in the refrigerator in its original wrapping. Small roasts will take three to five hours per pound, while larger roasts can take up to seven hours per pound. Thawing ground pork depends entirely on the thickness of its packaging.
It is safe to cook frozen or partially-frozen pork, but its cooking time may take 50 percent longer. Frozen pork should not be cooked in a slow cooker.
Sealed pork products can typically last in the fridge for two to four days, with ground pork having a slightly shorter shelf life at one to three. Ham or other smoked pork products like bacon can be stored for up to a week, though this only applies to products that aren’t vacuum sealed or prepared with preservatives. The latter can obviously last a lot longer.
Spread the remaining mushroom mixture over the roast. 
Lay the rest of the prosciutto slices, in the same manner as before, over the mushroom mixture. 
Fold up the edges of the plastic wrap and use another piece of plastic to enclose the entire roast; refrigerate.
Lay the rolled-out pastry over the roast. 
Use a spatula to lift up the pastry base, then tuck the sides of the uncooked pastry underneath the cooked pastry to seal the roast. 
Brush the pastry all over with the reserved egg. 
Roast for 20 minutes. Lower the oven temperature to 400°F and continue to roast for 25 minutes more for rare to medium-rare beef, 30 to 35 minutes for medium. Remove the Wellington from the oven and let it stand for about 10 minutes before slicing.
