Since the 17th century the United Kingdom has been one of the world's largest consumers of tea, with an average annual per capita supply of 1.9 kilograms (4.2 lb). Originally an upper-class drink in Europe, tea gradually spread through all classes, eventually becoming common. It is still considered an important part of the British identity and is a prominent feature of British culture and society.
In Northern Ireland and in the rest of the United Kingdom tea drinking blends and preferences vary. Although typically served with milk, it is also common to drink certain varieties black or with lemon. Sugar is a popular addition to any variety. Everyday tea, such as English breakfast tea, served in a mug with milk and sugar is a popular combination. Sandwiches, crumpets, scones, cake, or biscuits often accompany tea, which gave rise to the prominent British custom of dunking a biscuit into tea.
