Pastry: Sift the
flour, confectioners' sugar, and salt into a medium
bowl. Cut in the butter until the mixture
resembles coarse crumbs.
-
Add the egg and enough
water to form a dough. Divide the dough in half.
Wrap in plastic wrap, and refrigerate for 30
minutes.
-
Preheat the oven to 400°F/200°C/gas 6. Set out four 12-cup mini muffin pans. Roll out the
dough on a lightly floured surface to a thickness of
1/8 inch (3 mm).
-
Use a 2-inch (5-cm) round cookie
cutter to cut out rounds. Gather the dough scraps,
re-roll, and continue cutting out rounds until there
are at least 48 rounds.
-
Press the rounds into the
prepared cups and prick all over with a fork.
-
Bake
for 8-10 minutes, or until the pastry is pale gold.
Cool completely in the pans. Drop 1/2 teaspoon
of the orange curd into each pastry base.
-
Meringue
Topping: Stir the egg whites, water, cream of
tartar, and salt in a double boiler until blended.
-
Cook over low heat, beating constantly with a
handheld electric mixer at low speed until the
mixture registers 160°F (71 °C) on an instant-read
thermometer.
-
Transfer to a bowl and beat at high
speed, gradually adding the superfine sugar until
stiff peaks form. Fit a pastry bag with a 1/2-inch
(1-cm) star tip.
-
Fill the pastry bag with the
meringue and squeeze over the tarts in a decorative
manner.
-
Bake for 6-8 minutes, or until lightly
browned. Cool completely in the pans. Decorate
with the orange curls and dust with confectioners'
sugar.
