As I can't convert you to trying Murphys or Beamish once again, I'll try and explain something about the Waterford Blaa. Back in the day when we lived in Waterford we used to buy our blaas on Ballybricken (corner shop across the road from the Garda Station). They were affordable, fresh and available always. It was worth driving to Ballybricken early just to get the blaas fresh for your immediate breakfast. The blaas were magnificently tasty. Some people had more fondness for the lower section of the blaa although I preferred the top.
Soft white bread rolls are insipid next to the blaas. I've seen "Waterford Blaas" recently in Dunnes Stores - they fall down on the job on taste, size, appearance, smell and feel.
I've tried baking the Waterford Blaas from a recipe using Strong Flour and still were not as good as the blaas I used to buy in Ballybricken.
