Meringue hats sitting atop a shortcrust pastry sandwiched with jam
- 280 g all purpose flour
- 50 g sugar
- 1 teaspoon lemon zest
- 1 teaspoon vanilla extract or my preference — vanilla bean paste
- 250 g unsalted butter at room temperature
- 3 large egg yolks
- pinch of salt
- 3 large egg whites at room temperature
- 250 g powdered sugar
- pinch cream of tartar optional, helps meringue form
- In the bowl of a stand mixer, combine flour, sugar and lemon zest. Add butter and vanilla and mix with the paddle. Add egg yolks one at a time and continue to beat until dough starts to come together. Transfer to a work surface and knead by hand for another minute until smooth. Divide the dough in two, wrap in saran wrap and chill for one hour.
- Preheat oven to 300°F. Line 2 cookie sheets with parchment paper or silpats.
- Beat egg whites and cream of tartar at medium speed until foamy. Add powdered sugar and continue to beat until stiff peaks form, about 10 minutes. Fill piping bag with meringue closed star tip or plain round one.
- Roll out the dough between two pieces of parchment to 3mm thickness. Cut out with 1½" inch round or linzer cookie cutters and place on cookie sheets. Only re-roll scraps once. Chill for 20 minutes. Pipe the meringue on each cookie with one fluid squeeze — not a beehive pattern. Bake at 300°F for about 20 minutes but watch them. Pull them out when they are just golden on the bottom of the cookie. Cool on racks and sandwich together with your favorite jam– apricot and plum lekvar are popular ones. Keep at room temperature for 2 weeks.
