These cookies are a favorite in my home and the first to disappear at family parties. I make a few adaptations when I make them, though. First, I use white all-purpose flour instead of pastry flour. Due to the stickiness of the dough, I add about a quarter cup more flour to the recipe. I also throw in half a bag (about a cup?) of white chocolate chips. I add slightly more orange zest than what is called for, and naturally squeezed orange juice from the orange that I am zesting. I flour my hands before I begin rolling a small amount of dough into an inch-sized ball in my hands to help with the stickiness before rolling in in the extra sugar. Serve them at a party, and these cookies will leave your guest begging for more!
