What is "tea sandwich"?

A tea sandwich is a small, delicate sandwich that is typically served as part of an afternoon tea service. The sandwich is made using thinly sliced bread that has been trimmed of its crusts and filled with a variety of ingredients, such as cucumber, cream cheese, smoked salmon, or egg salad. The sandwich is often cut into small, bite-sized pieces and arranged on a serving platter alongside other tea-time treats, such as scones and pastries. Tea sandwiches are a popular food item in many cultures around the world and are often enjoyed as a light and elegant snack.
