When you are travelling in Cork, try Middleton Farmers Market, Sat mornings. Arbutus breads are there, quite good. Also in Dublin, there is Soul Bakery, they are based in Clonee, though do attend most farmers markets in the Dublin area. As well as Farmers Markets in Ireland (local, organic produce) there are also County markets, my local town has one on a Friday morning. It's fantastic for traditional breads, cakes, scones, savoury and sweet tarts, home-made jams, the sort of things everyone in Ireland used to make years ago, but don't have the time. It's in Portumna, Co Galway which is on the River Shannon, though there are plenty of these dotted around Ireland which might be what you are looking for.
