Blaas are terrific bread rolls from Waterford, where I'm from. They are the only indigenous Irish yeast bread and are a source of county pride. We love them. A blaa is a fluffy white bread roll with a floury top, so expect to get a flour moustache as you eat them. For perfect blaas - such as those from Waterford - make sure the rolls are baked very close together so they join, which leaves them with soft sides as you pull them apart.
