unarrested development – lemon ‘mac’ cookies

Lemon Macaroons

1. Adjust oven rack to middle position and heat oven to 375℉. Line 2 baking sheets with silpat or parchment paper. In a medium bowl, combine the coconut with the sweetened condensed milk, vanilla, and lemon zest. In another bowl, using an electric mixer, beat the egg whites with the salt until firm peaks form. Fold the beaten whites into the coconut mixture.

2. Scoop tablespoon-size mounds of the mixture onto the baking sheets, about 1 inch apart. Place one sheet of macaroons in oven and bake until golden, about 25 minutes. (Rotate tray front to back half way through baking). Transfer the baking sheet to rack and let the macaroons cool completely. Repeat with the 2nd sheet of macaroons.

Lemon Curd Filling

1. Dissolve gelatin in 2 teaspoons lemon juice in a small bowl, set aside. Heat remaining lemon juice, sugar, and salt in medium non-reactive saucepan over medium-high heat, stirring occasionally, until sugar dissolves and mixture is hot but not boiling. Whisk eggs and yolks in 2-cup glass measuring cup. Whisking constantly, slowly pour hot lemon-sugar mixture into eggs, then return mixture to saucepan.

2. Cook over medium-low heat, stirring constantly with heatproof spatula, until mixture registers 170 degrees is thick enough to leave trail when spatula is scraped along pan bottom, about 2 minutes. Immediately remove pan from heat and stir in gelatin mixture until dissolved. Stir in cold butter until incorporated. Pour filling through fine-mesh strainer into non-reactive bowl. Cover surface directly with plastic wrap; refrigerate until firm enough to spread, at least 1 hour.

Lemon Sablés

1. Crack egg and peel shell. Separate yolk from white; discard white. Press yolk through fine-mesh strainer into small bowl.

2. In bowl of stand mixer fitted with paddle attachment, beat butter, granulated sugar, salt, and cooked egg yolk on medium speed until light and fluffy, about 4 minutes, scraping down sides of bowl and beater with rubber spatula as needed. Turn mixer to low, add vanilla, and mix until incorporated. Stop mixer; add flour and mix on low speed until just combined, about 30 seconds. Using rubber spatula, press dough into cohesive mass.

3. Pat dough into a 6-inch disk, about 1 inch thick, and wrap in plastic wrap. Chill until firm, about 1 hour.

4. Adjust oven to middle position and heat oven to 350℉. Line 2 rimmed baking sheets with parchment paper. Remove disk of dough from refrigerator and roll out on floured work surface to about 1/4-inch thick. Using a 2-inch fluted cookie cutter, cut out 36-40 cookies and place on prepared baking sheets, about 1-inch apart.

5. Bake one sheet at a time (refrigerate or freeze the 2nd sheet) until centers of cookies are pale golden brown with edges slightly darker than centers, about 15 minutes, rotating baking sheets front to back halfway through baking. Cool cookies on baking sheet 5 minutes; using thin metal spatula, transfer cookies to wire rack and cool to room temperature.

Assembly

1. Spread 1 teaspoon of lemon filling on a cookie and top with a lemon macaroon. Repeat with remaining cookies. Cookies can be refrigerated between wax paper in airtight container for up to 1 week.
