A pig roast or hog roast is an event or gathering which involves the barbecuing of a whole hog (the castrated male pig or boar, bred for consumption at about 12 months old). Pig roasts in the mainland Deep South of the United States are often referred to as a pig pickin', although roasts are also a common occurrence in Puerto Rico and Cuba as well as the non-mainland US state of Hawaii (a luau), with roasts being done in the mainland states by descendants of other areas. A pig roast is traditional meal in Serbia and Montenegro, often prepared for celebration events and family fests, and it can be usually found on the menu of traditional taverns and bars - kafana.
The tradition of the pig roast goes back millennia and is found in many cultures. There are numerous ways to roast pork, including open fire rotisserie style roasting, and "caja china" style box grilling. Many families traditionally have a pig roast for Thanksgiving or Christmas. In Miami and other areas with large Cuban, Puerto Rican, Honduran or other Caribbean populations pig roasts are often held on Christmas Eve by families and friends whereas families from Hawaii often hold a roast on memorial day.
Pig roast (lechon asado) is a part of Puerto Rico's national dish and is usually served with arroz con gandules. In Puerto Rico, pig roasts occur year round, but happen in greater frequency as part of New Year's Eve celebrations and especially Christmas; occasionally if a family has relocated to the cities of the United States, they will take the recipe with them and use it during the summer. In the Dominican Republic, "puerco a la puya" is a traditional part of the Christmas Eve meal.
In the Philippines, the roasted pig is referred to as lechon baboy. It is traditionally prepared for Christmas celebrations but is also commonplace at birthday parties, weddings, debuts, and family reunions.
