A Colston bun is a sweet bun made of a yeast dough flavoured with dried fruit such as currants, candied peel, and sweet spices. It is made in the city of Bristol, England, and named after Edward Colston, a local merchant and MP, who created the original recipe. There are two size categories: "dinner plate", with eight wedge marks on the surface, and "ha'penny staver", an individual-sized bun.
