Afternoon tea is a British tradition that dates back to the 19th century. It involves taking a light meal or snack with tea in the afternoon, typically between 3 and 5 pm. 

This social gathering usually includes a selection of finger sandwiches, scones with clotted cream and jam, cakes, pastries, and sometimes savory items like quiche or vol-au-vents. 

The tea served can range from classic black teas to more floral varieties like Earl Grey or Darjeeling.

The atmosphere of an afternoon tea is often elegant and leisurely, with participants seated at tables set with fine china and perhaps adorned with linen napkins and silverware. 

It's an occasion for conversation and relaxation, and it can be both a formal event, such as at a hotel or tearoom, or a more casual gathering among family and friends.

Afternoon tea has evolved over time but remains a beloved ritual that showcases British culture and etiquette. Today, it is enjoyed not only in the UK but also around the world as a special treat or celebration.
