Anyway, here you go -

85g / 3oz raisins
115g / 4 oz butter or sunflower marg, melted
Preheat oven to 190 / Gas 5
Lightly brush a 28 x 18 cm shallow baking tray with the oil. combine all dry ingredients with melted marg / butter in a bowl. transfer mixture to baking tray and press down firmly with the back of a spoon. Bake for 15 - 20 mins or until golden.
score with a sharp knife while still warm and leave to cool in tin for 10 mins, then transfer to a wire rack.
