We loved these cookies, but they were very hard to roll out. The dough was crumbly and I kept having to piece it together. Also the baking time is way too long. I rolled them out perhaps 1/4 inch thick and baked them for 11 minutes total, rotating the pans halfway through. The next time I make it, I plan to try a whole egg rather than just one yolk to see if that solves the crumbling dough problem. The flavor is very good, though.
