# How to Make It:

01 - Preheat oven to 350°F. Line a baking sheet with parchment paper.
02 - In a mixing bowl, combine flour, sugar, salt, and cold butter cubes. Rub mixture between your fingertips or use a pastry cutter until texture resembles coarse breadcrumbs.
03 - Spread mixture evenly on prepared baking sheet. Bake for 12 to 15 minutes, stirring halfway through cooking time, until golden brown. Remove from oven and allow to cool completely.
04 - In a heatproof bowl, whisk together egg yolks, 1/4 cup sugar, lemon juice, and lemon zest. Position bowl over a pot of simmering water, creating a double boiler. Whisk constantly for approximately 7 minutes until mixture thickens. Remove from heat and cool to room temperature.
05 - In a clean mixing bowl, beat egg whites with cream of tartar using an electric mixer until soft peaks form. Gradually add remaining 1/4 cup sugar while beating until stiff peaks form.
06 - In a separate bowl, whip chilled heavy cream until soft peaks form.
07 - Gently fold whipped cream into cooled lemon mixture using a rubber spatula. Then fold in egg whites until just combined and smooth, taking care to preserve airiness.
08 - Spoon generous layer of cooled shortbread crumble into bottom of 6 serving glasses or ramekins. Top with lemon mousse, dividing evenly among servings.
09 - Refrigerate assembled cups for minimum 2 hours before serving. Top each cup with fresh berries, lemon zest curls, and mint leaves immediately before presentation.
