Mixing: This recipe is great for doing by hand; however, you can use a stand mixer on a low setting - this is very helpful when adding the dry ingredients.
Freezing: Dough is perfect for freezing if you want to make ahead. You can form a log with dough and wrap in plastic or you can form into balls, freeze on cookie sheet then transfer to a freezer bag. Allow frozen dough to come to room temperature before baking. If freezing in balls, allow them to thaw on a cookie sheet, not in the freezer bag.
