Method
In a large mixing bowl, beat the softened 225g of butter and confectioners' sugar together until pale and creamy.
Mix in the vanilla extract, then fold in the all-purpose flour and salt just until a cohesive dough forms. Do not overmix, or the shortbread will become tough.
Shape the dough into a cylindrical log approximately 5 cm in diameter. Wrap tightly in parchment paper or plastic wrap and refrigerate for at least 2 hours until completely firm.
Preheat the oven to 90 degrees C (195 degrees F). Whip the egg white in a clean bowl until soft peaks form, then gradually add the 50g of granulated sugar, whipping constantly until the meringue holds stiff, glossy peaks.
Spread the meringue into a thin, even layer on a parchment-lined baking sheet. Bake for 1 hour until entirely crisp and dry, then set aside to cool before shattering into small shards.
While the meringue bakes, prepare the curd. In a heatproof bowl set over a saucepan of gently simmering water, whisk together the egg yolks, 100g granulated sugar, lemon zest, and lemon juice.
Cook the lemon mixture, whisking constantly, until it thickens enough to coat the back of a spoon. Remove from heat and stir in the chilled 60g of butter until melted. Pass through a fine mesh sieve into a clean bowl, cover the surface directly with plastic wrap, and chill.
Preheat the oven to 175 degrees C (350 degrees F). Remove the chilled dough log from the refrigerator and use a sharp knife to slice it into rounds about 1 cm thick. Space them 3 cm apart on a lined baking sheet.
Bake the shortbread rounds for 12 to 14 minutes until the centers are set and the bottom edges are just beginning to turn golden. Transfer to a wire rack to cool completely.
Once all components are fully cooled, assemble the cookies by placing a generous dollop of lemon curd in the center of each shortbread round. Sprinkle with shards of the crispy meringue and serve immediately.
Chef's Notes
- Assemble these cookies à la minute. The stark contrast between the crisp shortbread, the brittle meringue, and the lush curd is the soul of this dessert, and moisture transfer will ruin the effect if they sit.
- Using confectioners' sugar instead of granulated sugar in the shortbread dough reduces gluten development and prevents spreading, resulting in an incredibly tender, melt-in-your-mouth cookie.
- This recipe naturally utilizes the whole egg: the yolks provide richness and setting power to the curd, while the leftover white aerates into the crunchy meringue topping, making it a zero-waste process.
- Always pass your lemon curd through a fine mesh sieve. Even with meticulous whisking, tiny chalazae (the white strings in eggs) or rogue bits of cooked yolk can ruin a perfectly silky texture.
Storage
Refrigerator: 3 days — Store cookies, curd, and meringue in separate airtight containers. Assembled cookies will become soggy within a few hours.
Freezer: 1 month — Unbaked shortbread dough logs freeze exceptionally well. Thaw overnight in the refrigerator before slicing.
