Here is a really simple recipe (from Australian Women's Weekly) for a sweet treat. In a food processor blend 300g butter, 220g caster sugar and 375g plain flour until mixture just comes together. Add 125g dried cranberries, mix. Press into a greased tin approx 26 x 32cm. Brush surface with beaten egg white and sprinkle with about 2 Tbsp caster sugar. Bake at 150deg C (130 for fan oven) for about 40 mins or until golden and crisp. Cut into pieces and cool in tin.
