The Waterford blaa has held EU Protected Geographical Indication status since 2013, the same kind of protection that covers products like Melton Mowbray pork pies.
A soft white roll, heavily dusted in flour with almost no crust, is baked fresh each morning and split for sandwiches — traditionally packed with sausages, rashers, or just butter. Waterford's bakeries and market stalls sell them warm, often selling out by mid-morning.
