Irish breakfast is a traditional meal consisting of fried eggs, vegetables, potatoes, and meats such as bacon, sausages, and both black and white puddings. The large meal is almost always served with Irish soda or brown bread, a cup of tea, and a glass of orange juice on the side.
All of the ingredients are most commonly fried in creamy butter. Originally, the breakfast was invented as a way to prepare the people for a day of hard work on the farm, and the meal was especially popular on cold winter mornings. Today, its huge size is making it somewhat impossible to consume on most working day mornings, so it is usually prepared on Sunday morning (or Christmas morning, when it's especially popular).
