The bacon is traditionally fried. Poached or scrambled eggs and perhaps grilled bacon may be offered as alternatives. Some of the additional ingredients that might be offered as part of a "full English breakfast" include: pork sausages; black pudding; fried or grilled tomatoes; mushrooms; fried bread or possibly sauté potatoes; baked beans; kidneys; and bread and butter on the side. In Scotland you might be served "square sausage" and in Ireland you might get white pudding and soda bread.
A full English breakfast served at a hotel might offer additional courses consisting of a choice of cereal, porridge, kippers; toast and jam; kedgeree or devilled kidneys. You would also expect to be served with coffee or tea and fruit juices.
