Preheat oven to 350 degrees F (180 degrees C). Butter (or spray with a non
stick vegetable spray) a 9 x 13 inch (23 x 33 cm) baking pan.
In the bowl of your electric mixer (or with a hand
mixer), beat the butter and vanilla extract until smooth and creamy (about
one minute). Add the
sugar and beat until light and fluffy. In a separate bowl whisk the flour with
the salt and then
add the flour mixture to the butter mixture and beat
until the dough just comes together.
Divide the dough into two halves, making one half slightly larger than the other
half. Spread the smaller half of dough
over the bottom of the prepared pan and gently press the dough, with your
fingertips or the back of a spoon, to form an even layer. Sprinkle the raisins
evenly over the dough and gently press the raisins into the dough. Take the
other half of dough and
using your fingers, crumble
it over the top of the raisins. Then lightly press the dough into an even layer.
Take the lightly beaten egg and, using a pastry brush, coat the top of the
shortbread with the egg wash. Then, with the tines of a fork, slowly drag the
fork back and forth across the shortbread to make a decorative pattern.
Bake the shortbread for about 30 - 40 minutes or until light golden brown.
Remove from oven and place on a wire rack to cool. Cut the shortbread into about
1 x 3 inch (2.5 x 7.5 cm) rectangular bars.
