Is it sc(oh)ne? or sc(ah)ne?

Either way, while in Ireland we had the best scones I've ever tasted. At Clontarf Castle to be precise. We had just arrived in Dublin (took the red-eye from Washington DC), and were looking forward to breakfast. Oh course, they had just finished serving. We were told we could get a light snack in the lounge. Tea and scones, heaven! The scones were large and fluffy and piping hot. So good. As a result, when we had afternoon tea at the Dorchester in London and The Pump Room at the Roman Baths in Bath we couldn't help but compare the scones and be just a wee bit disappointed.
