A Boston bun, also known as a Sally Lunn, is a large spiced bun with a thick layer of coconut icing, prevalent in Australia and New Zealand. Traditionally the bun contains sieved mashed potato,[1] and modern versions sometimes contain raisins or sultanas, the inclusion of which dates from the 1930s.[2] Records for the sale of a product named "Boston Bun" can be found dating from the early 20th century.[3] It is often served sliced and buttered, to accompany a cup of tea. The origin of the name is unknown.[4] In the North Island of New Zealand, it is also known as a "Sally Lunn", although it has no relation to the traditional English bun of the same name.
