The bun is one of London’s oldest culinary treats, tracing its roots back to the early 18th century, when it was said to have been first baked at a property later known as the Chelsea Bun House, near where Royal Hospital Road runs today, which was popular with Hanoverian royalty. According to legend, an estimated 50,000 queued to buy them on one Good Friday such was the popularity of a delight written about by Jonathan Swift, Charles Dickens and Lewis Carroll.
