Heat the oven to 325°F. Beat the butter and sugar together with a wooden spoon or a mixer until creamy. Add the lemon zest, lemon juice, and salt; mix until combined. Add the flour; mix until just blended. Shape the dough into 1-inch balls and set them 1 inch apart on ungreased or parchment-lined baking sheets. Bake until the cookies are light golden and give slightly when pressed, 18 to 20 minutes. Let the cookies cool slightly on the baking sheet; while still warm, roll them in confectioners’ sugar. Transfer to a rack to cool completely.
