From Celtic Cookery, by Iris Price Jones. "The Welsh name for these is Pice ar y Maen. I'm not sure what the derivation of Pice is, but Maen means stone - the bakestone or griddle that the cakes are cooked on. This method of baking, with the closer contact with heat than when baking in the oven seems to accentuate the flavour and to give the cakes a lovely brown crust". A large heavy frying pan is a good substitute for a griddle.
