OK, so the hors d'oeurves musta been kind of good because all of them were gone by the end of the dinner party last night. I was just bummed that they all looked the same, but were different things. The pastry flour worked wonders on the crust for the leek tarts as they were melt in your mouth good. People seemed to like the shape and feel of the "potato cookies" which were essentially spoon dropped onto baking sheets and left to melt into a puddle shape. The gruyere really made the potato puffs excellent.
