Cuban cuisine has been influenced by Spanish, French, African, Arabic, Chinese, and Portuguese cultures. Traditional Cuban cooking is primarily peasant cuisine that has little concern with measurements, order and timing. Most of the food is sauteed or slow-cooked over a low flame. Very little is deep-fried and there are no heavy or creamy sauces. Most Cuban cooking relies on a few basic spices, such as garlic, cumin, oregano, and bay laurel leaves. Many dishes use a sofrito as their basis. The sofrito consists of onion, green pepper, garlic, oregano, and ground pepper quick-fried in olive oil. The sofrito is what gives the food its flavor. It is used when cooking black beans, stews, many meat dishes, and tomato-based sauces. Meats and poultry are usually marinated in citrus juices, such as lime or sour orange juices, and then roasted over low heat until the meat is tender and literally falling off the bone.
