For extra lemon punch, increase the zest to 1.5 tablespoons or finish warm cookies with a light lemon glaze made from powdered sugar and lemon juice; avoid overbaking to keep centers soft—pull them when edges are set but centers look pale, as they continue to firm up while cooling. If dough feels sticky after chilling, chill an additional 10 minutes; conversely, if too firm to scoop, let sit at room temperature for 5 minutes. Use room-temperature butter and egg for best texture, and weigh flour (270 g) to prevent dry cookies. These freeze well: freeze scooped dough balls up to 2 months and bake from frozen adding 1 to 2 minutes.
