Saint Patrick's Pistachio Cookies
Grease baking sheets lightly instead of lining with parchment paper, if preferred.
Substitute vanilla extract with the scraped seeds of 1 fresh vanilla bean, or 1/8 teaspoon of pistachio flavoring.
I flatten the cookies with the end of the pusher from your food processor. If you don't flatten the cookies, they'll bake up in softly flattened mounds; they're lovely either way.
Reynolds® parchment can be used for easier cleanup/removal from the pan.
