A blaa /blæ/ is a doughy, white bread bun (roll) speciality; particularly associated with Waterford, Ireland. It is currently made in Waterford and County Kilkenny and was historically made in Wexford.The blaa is usually very soft and covered with white flour. This variety of blaa is more chewy, while the second popular variety has a crusty but tasty exterior. Blaas are sometimes confused with a similar bun, known as a bap, which is often served with less flour.
