This is a great recipe! I used about a quarter less butter and that may have made these a little less flaky. Upon re-reading the recipe just now I realized that I also forgot to brush them with egg before baking but they still came out golden and beautiful. I baked the first two quarters of dough and wrapped the others in plastic wrap and froze them. The frozen dough was just as good, if not even better. It thaws quickly on the counter or in the fridge and was a very easy item to take to a friend's pot luck. Another variation: sprinkle the triangles with sugar and cinnamon for a cinnamon roll croissant. Would be great with a cream cheese, powdered sugar and citrus drizzle.
