Method
Make shortbread cups
- Mix flour and powdered sugar, then cut in cold butter until sandy; stir in egg yolk and vanilla to form a dough. Press dough into a 24-cup mini muffin tin, covering the bottom and sides with an even thickness.
- Bake at 350°F for 12 min until the edges are set and lightly golden. Cool in the tin.
Make lemon curd
- Whisk egg yolks, lemon juice, and sugar over a double boiler until smooth and starting to thicken. Cook until thick enough to coat the back of a spoon, then remove from heat.
- Whisk in cubed butter until fully melted and glossy. Strain for a silky texture and cool to room temperature.
Assemble
- Fill each cooled cookie cup with lemon curd to the top edge.
- Heat egg whites and sugar over a double boiler until the sugar dissolves, then whip to stiff glossy peaks. Pipe swirls onto each lemon-filled cup, making peaks that hold their shape.
- Torch the meringue at close range until golden-brown on the tips. Refrigerate until ready to serve.
Notes
Strain the lemon curd after cooking to remove any cooked egg bits for a perfectly silky texture. For best texture, torch the meringue right before serving. Store assembled cups covered in the refrigerator up to 2 days; for best results, freeze unfilled cookie cups only (freezing meringue can weep after thawing). For a gluten-free swap, use a 1:1 gluten-free baking flour blend for the shortbread.
