The scent you'll be smelling wafting from Elizabethan backyards this Saturday will be grilled chicken with almond garlic sauce, the main course for the annual progressive dinner. Or, as we say in Greece, Kotopoulo stin skara me skordalia. They say the sauce was one of the first the Greeks made and can be traced back 2,500 years. That may be. But I'm making a fresh batch. See you at the appetizer house at 6.
