They're never baked in an oven — every Welsh cake is cooked on a flat griddle called a bakestone, the same way they were made in mining-village kitchens generations ago.
A spiced, currant-studded dough is rolled out, cut into rounds, and cooked on a hot griddle until lightly browned on both sides, then dusted with sugar. Market stalls and festival vans across Wales cook them fresh to order, handing them over warm in a paper bag.
