Sift the flour
and salt into a large bowl. Use a pastry blender
to cut in the butter until the mixture resembles
coarse crumbs.
Mix in the cream. Press the dough
into a disk, wrap in plastic wrap, and refrigerate
for 30 minutes.
Preheat the oven to
375°F/190°C/gas 3. Line two cookie sheets with parchment paper.
Roll out the dough on a lightly
floured surface to a thickness of 1/8 inch (3 mm). Use a 1 1/2-inch (4-cm) cookie cutter to cut out the
cookies.
Gather the dough scraps, re-roll, and
continue cutting out cookies until all the dough is
used. Use a spatula to transfer the cookies to the
cookie sheet, spacing them
1 1/2
inches (4 cm)
apart.
Bake for 8-10 minutes, or until just golden
at the edges. Transfer to racks to cool.
Pink Filling: Mix the confectioners' sugar, butter, cream,
vanilla, and red food coloring in a small bowl.
Stick the cookies together in pairs with the
filling. Dust with the confectioners' sugar.
