'Sarabeth's Bakery' on Serious Eats
Super light and flaky with just the slightest hint of lemon zest, these are some of the best shortbread cookies I've ever made. Unlike other recipes that can get overly cakey and crumbly to the point of falling apart, these roll out thin and bake up tender. The cookies are finished with a sprinkling of sugar immediately after they come out of the oven. The heat from the cookies adheres the sugar to the tops, giving them a tiny sugar crust.
