A special dish, cooked to mark a celebration, particularly the festival of Eid, Shuwa is cooked a day prior to when it will be consumed; this is tradition practised by many Omani families. The long preparation process is probably the reason for this practice; where the meat, which is often, lamb, camel or mutton, is marinated in an exotic blend of spices. Spices may change according to households but generally consist of coriander leaves, cumin and nutmeg. The meat wrapped in banana leaves is cooked in an underground oven for a day. The result is a soft and tender meat, with a crispy layer of spices on the outside.
