The origins of cobblers are unclear, but it is certainly an old idea. Scones (some say dumplings but I think they are wrong) are placed on top of a stewed fruit or meat filling and baked. I guess you might call it a primitive pie. Adding cheese to the scones gives them a whole extra flavour dimension. I think we'll call it oo-marm-ee.
Beaten egg with a splash of milk to glaze the scones.
