We threw away our recipes for potatoes au gratin, galette de pommes de terre, and pommes Anna, when we discovered this dish from Margaret Williamson.  It replaces both and is simply the best potato side dish you’ll ever encounter.  Margaret loves to clip recipes from various sources, having owned a catering business, and she is always trying something new.  This is one of the few recipes that she actually keeps with her on all of her travels, as it is always a hit with diners from Europe to the US.  It is simple to put together if you are quick with the potato peeling and slicing.  And then you just have to wait for the bubbling goodness to come out of the oven.
