One advantage of roasting is that many vitamins stay in the food rather than being cooked away. A disadvantage is that it takes a while for meat to roast thoroughly.
Roasting is best used for larger pieces of meat or some types of vegetables. It is a method that uses dry heat to cook the food item. Roasting does not require any special skills or equipment.
Roasting results in a tender final product, and there are a few different styles of roasting. Spit roasting is done over an open fire. The meat is continuously turned to ensure all food is evenly cooked. Pot roasting is done using a large pot. This method allows the juices to be retained for making gravy.
