I’m one of the Assistant County Archaeologists at Northumberland County Council, and I made this cake for a friend digging at Caerwent back in the ’90s. The top layer (top picture) shows a Roman site with a four-post structure, while below this are Iron Age (middle picture) and Neolithic (bottom picture) layers. I made sure all the best finds were under the spoil heap. I have subsequently adapted this design, simplifying the archaeology (using chocolate fingers) to help explain site depositional processes and excavation to schoolchildren. Whether they’re interested in archaeology or eating the cake, who knows…
