Preheat the oven to 350°F (175°C) and prepare a cookie sheet by lining it with parchment paper.
In a medium bowl, mix together the flour, baking soda, baking powder and salt.
In the bowl of a stand mixer fitted with the paddle attachment, beat together the butter and11/4 cups (310 ml) sugar until pale and fluffy, scraping down the side as necessary. Beat in the zest until well combined.
With the mixer on medium speed, add the egg, then the lemon juice, beating until incorporated. Add the flour mixture and mix on low speed until just combined.
Using a spoon, scoop out 1-inch (2.5 cm) balls of dough and roll them between your hands to form spheres.
Drop into a small bowl of the remaining 1/4 cup (60 ml) of sugar and roll gently with your fingertips to coat the dough on all sides.
Space the dough balls about 2 inches (5 cm) apart on the cookie sheet and bake until the edges are cooked but the tops are still puffy, about 8 to 10 minutes. The cookies will be barely golden at the edges and still look ever so slightly uncooked on top. Cool on the cookie sheet for a few minutes, until the tops have fallen and crinkled. Remove to a cooling rack.
