For the Cookies
- 1 stick plus 6 tablespoons unsalted butter, room temperature
- 3/4 cup confectioners' sugar, sifted
- 1 large egg yolk
- 1/4 teaspoon coarse salt
- 2 1/4 cups all-purpose flour
- 1/3 cup coarse sanding sugar
For the Filling
- 12 large egg yolks
- 1 1/2 cups sugar
- 1 tablespoon lemon zest (from 2 to 3 lemons)
- 1/2 cup plus 2 tablespoons lemon juice (from 4 lemons)
- 1/4 teaspoon salt
- 1 1/2 sticks unsalted butter, cut into small pieces
- 2 limes
Make the cookies: In the bowl of a mixer, beat together butter and confectioners' sugar on medium speed until combined, about 3 minutes. Reduce speed to low, and add egg yolk and salt. Mix to combine, about 2 minutes. Add flour and mix to combine, about 2 minutes.
Form dough into 1 1/4-teaspoon balls. Roll each ball lightly in water, then sanding sugar; shake off excess. Immediately make an indentation in center of each. Transfer to a parchment-lined baking sheet, cover with plastic wrap, and chill until firm, about 1 hour.
Make the filling: Prepare an ice-water bath. combine yolks, sugar, lemon zest, lemon juice, and salt in a medium saucepan. Cook over medium heat, stirring constantly, until mixture has thickened and coats the back of a spoon, 10 to 15 minutes. Remove from heat, and add butter, stirring until melted.
Immediately strain mixture through a fine sieve into a nonreactive bowl. Set over ice-water bath, and cover with plastic wrap, lightly pushing on surface of mixture to prevent a skin from forming. Refrigerate until set, about 1 hour.
Preheat oven to 325 degrees. Bake cookies for 22 minutes or until golden on bottom. Allow to cool slightly on baking sheets set on a wire rack.
Transfer filling to a piping bag fitted with a 1/2-inch tip (such as Ateco #6). Pipe about 1/2 teaspoon into center of each baked cookie. Zest limes directly over tops. Return to oven and bake for 1 minute.
