Preheat the oven
to 300°F/150°C/gas 3. Line three cookie sheets
with parchment paper.
Beat the egg whites in a
large bowl until frothy. Gradually add in the
confectioners' sugar until stiff, glossy peaks form.
Set aside two heaped tablespoons of the meringue in
a small bowl. Fold in the almonds, flour,
cinnamon, almond extract, and salt into the
remaining meringue mixture.
Form the dough into
small balls and place 1 inch (2.5 cm) apart on the
prepared cookie sheet. Coat each cookie top with
the reserved meringue.
Bake for
30-40
minutes, or until
just golden. Cool on the sheets until the cookies
firm slightly. Transfer to racks and let cool
completely.
Frosting: Mix the confectioners' sugar
and water in two separate bowl. Add drops of each
food coloring to each bowl. Drizzle over the tops of
the cookies.
