Here’s how to plan and execute your own oyster roast:
Getting Oysters
Figure that each guest will probably eat two dozen oysters each. Oysters can be purchased a day or two before the roast, but makesure you wash them and either store them in a refrigerator or on ice.
Building a Pit
If you have a fire pit with a grate overtop that will work, but if not you can use four cinder blocks and a piece of sheet metal. The piece of sheet metal should be about 4 square feet. Place a cinder block underneath each corner of the sheet metal.
Build a fire that matches the size of your cooking surface (the sheet metal) and start it 1½ hours to 2 hours before you plan on cooking the oysters. When the coals are glowing red hot, place the sheet metal over the coals and you’re ready to start cooking. Preheat the metal before adding the oysters.
Cooking the Oysters
Spread the oysters in a single layer on the sheet metal and cover with two layers of wet burlap ensuring that the burlap is not touching the fire. Although, it is called an oyster roast you are technically steaming them when you cover them with the wet burlap. (*Note: it may take a while to get burlap wet so start soaking it when you start the fire.) You’ll need 4 pieces of burlap so you can always have two soaking while the other two are being used for cooking.
Cook oysters for 2-6 minutes. Since sheet metal will be hot you may need a shovel to bring them to the table.
Eating Oysters
While roasted oysters are much easier to get open than the raw ones, you might still need a few items to make the process easier. You can purchase oyster knives for about $2-3 which help with prying them open. Also a thick set of cloth gloves will help avoid knife slips or cuts from an oyster shell.
To open the shell, insert the blade of the oyster knife into the opening between the top and bottom shell and twist the knife to pry the shell open. Slide the knife along the inside surface of the top shell to detach the muscle. Remove the top shell and slide the blade underneath the meat to detach the muscle from the bottom of the shell. Dip or Slurp as you please.
