Yield: 16 servings
Ingredients: 8 tablespoons (1 stick) unsalted butter, cut into small pieces, plus more for greasing the pan; 1 1/4 cups all-purpose flour; 1/4 cup confectioners' sugar; 1/4 cup packed dark brown sugar; 1/2 teaspoon kosher salt; One 14-ounce can sweetened condensed milk; 1 teaspoon lime zest plus 3/4 cup lime juice (from 5 to 6 limes); 4 large egg yolks; Pinch kosher salt; 3 large egg whites; 1 cup granulated sugar

Directions

Special equipment:

A candy thermometer; a kitchen blowtorch

For the cookie base.
Preheat the oven to 350 degrees F. Butter a 9-inch square baking pan and line with parchment paper, leaving a 2-inch overhang on 2 sides. In a large bowl using an electric mixer, beat the flour, confectioners' sugar, brown sugar and salt on medium speed until well combined. Add the butter and beat until the crumbs are evenly moistened. Tip the crumbs into the prepared pan and pat down to make an even base. Bake the base until deep golden and set, 20 to 25 minutes. Transfer to a rack to cool, about 30 minutes. For the filling: In a large bowl, whisk together the sweetened condensed milk, lime zest and juice, egg yolks and salt. Pour the mixture over the baked cookie base and spread it into an even layer. Bake the filling until just set, 8 to 10 minutes. Transfer to a rack to cool, about 30 minutes, then cover with plastic and refrigerate until firm, at least 4 hours. For the topping: Just before serving, make the topping. In a large bowl (or the bowl of a stand mixer fitted with the whisk attachment), add the egg whites. In a small saucepot fitted with a candy thermometer, heat the sugar and 1/4 cup water over medium-high heat without stirring. When the thermometer hits about 220 degrees F, beat the egg whites with an electric mixer on medium speed until just frothy and the yellowish hue has disappeared. When the sugar reaches 238 degrees F, increase the mixer speed to high and, with the mixer running, pour the sugar syrup into the bowl in a thin stream. Continue to beat the mixture until shiny, stiff peaks form and the mixture is cool, about 6 minutes. Scoop the meringue on top of the filling and use an offset spatula to swirl it around into decorative swoops and spikes. Using a mini (kitchen) blowtorch, toast the topping to an even golden brown. Cut into bars and serve.

Propane gas torches are highly flammable and should be kept away from heat, open flame and prolonged exposure to sunlight. They should be used only in well-ventilated areas. Follow torch manufacturer's instructions for use.
