Lemon Meringue Thumbprint Cookies with Torched Peaks
Buttery shortbread thumbprint cookies filled with silky lemon curd and topped with torched meringue peaks. Bright citrus and toasted marshmallow sweetness create an elegant three-part cookie that delivers complex flavor in every bite. The reserved egg whites ensure zero waste, making this an efficient showstopper for afternoon tea, dessert platters, or special occasions. What sets this version apart is the tempering technique that stabilizes the lemon curd and the torching step that caramelizes the meringue for depth.

Tips
Tempering the egg yolks is critical for food safety and preventing scrambled eggs; always add warm liquid slowly while whisking. This stabilizes the curd and creates that silky texture.
Refrigerate shaped cookies before baking so they hold their indentations and don't spread. The dough firms up and resists the filling weight.
Torch the meringue just before serving for the best contrast between caramelized exterior and marshmallow interior. Torching far ahead causes condensation.
Good to Know
Store cooled cookies (without meringue) in airtight container at room temperature up to 3 days. Add meringue topping day-of for best texture.
Prepare dough up to 2 days ahead, wrapped tightly. Make lemon curd up to 1 week ahead, refrigerated. Torched cookies best served within 2 hours of meringue application.
Serve at room temperature on dessert platters, with tea or coffee, or as part of a holiday cookie collection. Torched meringue peaks look striking.
Common Mistakes
Don't add lemon mixture to egg yolks too quickly to avoid scrambling.
Don't skip the 165°F temperature check; undercooked curd risks foodborne illness.
Don't indent cookies too deep or they'll collapse when filled; gentle thumb press is enough.
Don't torch meringue more than a few hours ahead or it will weep and lose its crispness.

FAQ
Can I make the lemon curd without a thermometer?
Yes, cook until the mixture coats the back of a spoon and a finger drawn through leaves a clear path. However, thermometer ensures 165°F for food safety with raw egg yolks.
What if I don't have a kitchen torch?
Place cookies under a hot broiler for 1-2 minutes, watching closely to prevent burning. Torch gives more control and caramel color, but broiler works.
How long can I keep filled cookies before torching?
Store filled, unmeringueed cookies refrigerated up to 2 days in airtight container. Add meringue and torch same day for best results and food safety.
