Since the 17th century, the United Kingdom has been one of the world's largest tea consumers, with an average annual per capita supply of 1.9 kilograms (4.2 lb).[1] Originally an upper-class drink in Europe, tea gradually spread through all classes, eventually becoming a common drink. It is still considered an important part of the British identity[2] and is a prominent feature of British culture and society.[3]
In Northern Ireland and in the rest of the United Kingdom, tea drinking blends and preferences vary.[4] 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.
