7 oz/200 g
semisweet/dark chocolate, finely grated
Method:
Heat the milk
in a small saucepan. Remove from the heat and
mix in the baking soda.
Sift the
flour, baking powder, and salt into a large
bowl. Stir in the sugar. Add the vanilla and 2
eggs.
Pour in the
oil and baking soda mixture and mix until
smooth. Press the dough into a disk, wrap in
plastic wrap, and refrigerate for 30 minutes.
Preheat the
oven to 350°F/180°C/gas 4. Butter three cookie
sheets. Roll out the dough on a lightly floured
surface to a thickness of 1/4 inch (5 mm).
Use a 2
1/2-inch (6-cm) diamond-shaped cookie cutter to
cut out the cookies. Continue cutting out
cookies until all the dough is used.
Transfer the
cookies to the sheets, placing them 1 inch (2.5
cm) apart. Brush with the egg white and sprinkle
with chocolate. Bake for 20 minutes, or until
golden.
