Fairy bread

Fairy bread is sliced white bread spread with butter or margarine and covered with "Hundreds and Thousands", often served at children's parties in Australia and New Zealand. It is typically cut into triangles. Although people had been putting hundred and thousands on bread and butter for some time, the first known reference to this dish as Fairy Bread was in the Hobart Mercury in April 1929. Referring to a party for child inmates of the Consumptive Sanitorium, the article proclaimed that "The children will start their party with fairy bread and butter and 100s and 1,000s, and cakes, tarts, and home-made cakes..."
