1. Preheat the oven to 175C/350F. Mix the flour, baking soda, icing sugar and salt together in a mixing bowl. Rub shortening into dry ingredients until mixture looks like loose crumbs.

2. Place the dough between two sheets of plastic film, and roll it out into a rectangle, about 2mm thick. Divide it into 24 equal rectangles and prick the tops with a fork. Then use the back of a knife to make two vertical marks on the surface. Lightly brush them with egg white and then bake in the center of hot oven for 25 minutes.
