Know Your Guests?

Know your guests when you are serving the roast pork because everybody likes crackling and if you aren’t careful you will quickly run out of that of the road. Also, guests may vary in their appetite levels. You might want to rethink serving large portions at your family gathering if they tend to be heavy eaters. If it’s food for a sporting event, then everyone will be starving by the end of the game. Remember that kids eat smaller portions than grownups. So take that into consideration.

Know How Much Raw Pork Shrinks To Buy The Right Amount

When cooking any meat the difference between raw and cooked weights is called the yield. This is a calculation of the percentage that goes missing due to

  • shrinkage – moisture lost during cooking
  • trimming fat
  • any bone in the meat – e.g Roast Pork Shoulder can have bone in

The yield is what’s leftover to serve.

For boneless pork roast use an average of 32% weight loss due to cooking. For bone-in cuts it can be as high as 40% or more.

The above figures are what I use – but if you want to get super accurate and explore more data then the U.S Department of Agriculture has more detail again on Cooking Yields for Roast Pork.

Final Tips for serving Pork Roast for 50 Guests at a party.

The first thing that comes to my mind when I think about parties is food. Food is always a good way to start a party. It’s easy to make and it can be made ahead of time so you don’t have to worry about cooking for hours.

Another great idea is to serve finger foods like mini-pizzas, mini-sandwiches, and mini-desserts. These are perfect because they are small and portable.

A third tip is to keep the menu simple. Don’t try to do too much. Just stick to appetizers, salads, sandwiches, desserts, and drinks.

Don’t worry about being perfect.
