In Chapter Four of Happy Birthday, Molly!, Molly learns what Emily would do for her birthday tea party if she was in England.
In England they have real tea, and Emily suggests that she and Molly could put a lot of milk and honey in the tea. The English have thin tea sandwiches (with the crusts cut off!) and are either meat paste (ground up meat like ham or liver) or watercress, or even bread and margarine as butter was rationed. Emily also says she'd have a lemon tart for a special tea party.
