Petite Lemon Curd Cookies

Petite Lemon Curd Cookies

 

yield: Makes 6 to 7 dozen cookies

 

For cookies

2 cups all-purpose flour

1/2 teaspoon baking powder

1/2 teaspoon salt

1 1/2 sticks (3/4 cup) unsalted butter, softened

1 cup sugar

1 large egg

1/2 teaspoon vanilla

 

Whisk together flour, baking powder, and salt in a small bowl.

Beat together butter and sugar in a large bowl with an electric mixer at medium-high speed until pale and fluffy, about 3 minutes in a standing mixer (preferably fitted with paddle attachment) or 6 with a handheld. Beat in egg and vanilla. Reduce speed to low, then add flour mixture and mix until just combined.

Form dough into a 12-inch log (2 inches in diameter) on a sheet of plastic wrap and roll up dough in plastic wrap. Chill dough on a baking sheet until firm, at least 4 hours. (To roll cookies into balls, see cooks' note, below.)

Put oven racks in upper and lower thirds of oven and preheat oven to 375°F.

Cut enough 1/8- to 1/4-inch-thick slices from log with a heavy knife to fill 2 ungreased large baking sheets, arranging slices about 1 inch apart (chill remainder of log, wrapped in plastic wrap). If garnishing with coarse sugar, sprinkle slices with it.

Bake cookies, switching position of sheets halfway through baking, until edges are golden, 12 to 15 minutes total. Cool on sheets 3 minutes, then transfer with a metal spatula to racks to cool completely. Make more cookies with remaining dough on cooled baking sheets.

• Dough log can be chilled up to 5 days or frozen, wrapped in a double layer of plastic wrap, 1 month. If frozen, thaw dough in refrigerator just until it can be sliced.
• Instead of forming dough into a log and chilling, you can roll tablespoons of dough into 1 1/4-inch balls, then roll balls in finely chopped nuts (about 1 cup) and coarse sugar. Bake, switching position of sheets halfway through baking, until bottoms are browned, about 15 minutes total.
• To garnish cookies with chocolate, melt 3 1/2 oz chocolate and cool slightly. Transfer to a heavy-duty sealable plastic bag and snip a 1/16-inch opening in 1 corner. Pipe chocolate evenly back and forth over cookies. Let chocolate set before storing cookies.
• Cookies keep, layered between sheets of wax paper or parchment, in an airtight container at room temperature 1 week.

1 1/2 cups confectioners sugar for dredging and dusting

Special equipment: a 1 1/4-inch round cookie cutter; a pastry bag fitted with small plain tip or a heavy-duty sealable plastic bag (not pleated)

Preparation

Prepare cookie dough:
Follow recipe for basic butter cookies, forming dough into 2 balls (instead of a log) and flattening each into a 6-inch disk. Chill disks, wrapped in plastic wrap, until firm, at least 1 hour.

Roll out dough:
While oven preheats, roll out 1 piece of dough (keep remaining dough chilled) into a 9-inch round (slightly less than 1/4 inch thick) on a well-floured surface with a well-floured rolling pin. (If dough becomes too soft to roll out, chill on a baking sheet until firm.) Cut out as many cookies as possible with cutter.

Bake cookies, switching position of sheets halfway through baking, until edges are golden, 8 to 10 minutes. Dredge warm cookies in confectioners sugar until coated and transfer to a rack to cool completely. Make more cookies in same manner.

Transfer lemon curd to pastry bag or plastic bag (snip an 1/8-inch opening in a corner of plastic bag). Put 1 cookie upside down on work surface and pipe about 1/2 teaspoon lemon curd onto cookie, then top with another cookie, right side up, to form a sandwich. Make more sandwiches in same manner.

Just before serving, sift some remaining confectioners sugar over tops of sandwiched cookies.

Cooks' notes: • Cookies (baked and coated with confectioners sugar but not filled with lemon curd) keep, layered between sheets of wax paper or parchment, in an airtight container at room temperature 1 week. • Lemon curd (before filling cookies) can be made 1 day ahead and chilled, covered. • Sandwiched cookies (without additional confectioners sugar) keep, layered between sheets of wax paper or parchment in an airtight container, chilled, 4 days.

 

 

For lemon curd

 

• 3/4 cup fresh lemon juice
• 1 tablespoon finely grated fresh lemon zest
• 3/4 cup granulated sugar
• 1 stick (1/2 cup) unsalted butter, cut into bits
• 2 tablespoons cornstarch
• 1/2 teaspoon salt
• 4 large egg yolks

Make lemon curd:
Simmer lemon juice, zest, sugar, butter, cornstarch, and salt in a 2-quart heavy saucepan over moderately high heat, whisking constantly, 1 minute. Lightly beat yolks in a small bowl, then add 1/4 cup lemon mixture, whisking. Add yolk mixture to remaining lemon mixture, then reduce heat to low and cook, whisking constantly, until curd is thick enough to hold marks of whisk, about 2 minutes. Transfer to a bowl, then cover surface with plastic wrap and chill while rolling out dough.
