Preheat oven to 350 degrees. With a fork, mix flour, baking powder and salt then set aside. Using a hand mixer, combine butter, sugar, orange/lemon zest and orange/lemon juice. Mix until creamy and smooth. Incorporate the eggs one at a time. Add the dry flour mixture and mix until fully incorporated.Roll dough into one inch balls and place two inches apart on a greased cookie sheet. Bake for twelve to fifteen minutes then remove and cool for five minutes. Transfer to wire racks for cooling and glazing.
Zesty Glaze:Whisk together the juice of half of an orange, juice from one and a half lemons, the zest of one lemon & one orange and approximately two and a half cups of powdered sugar. This glaze will be thin and will lightly coat the cookies. If you prefer a thicker glaze just add more powdered sugar until the desired consistency.
