I adapted these to be orange flavored, so I feel as if I can't fairly rate it because I changed the recipe. I feel as if this recipe should specify that salted butter should be used. I literally had these mixed and ready to shape before I realized there was no salt in the recipe. I then remembered from another baking seizure that salted butter is often used in shortbread because table salt will be crunchy in the final cookie. I had to add some, cookie was very bland without. I think some of the other bakers who struggled with the flavor may have used unsalted butter.

Just made these for the first time. I shaped some according to the recipe's directions. I also experimented with a cookie press with the attachment I use for making cheese straws. Perfect! This will be one of my go-to recipes. They came out delicate and crisp, but did not crumble/fall apart as some others say they experienced. I'll glaze the cookies and dust the straws with powdered sugar.
