Preheat the oven to 180 degrees C. Lightly grease baking trays.
In a medium bowl, cream together the butter, white sugar, eggs, cinnamon, nutmeg and cloves. Combine the flour, bicarb soda and currants, and stir into the butter mixture alternately with tablespoons of milk until the flour is fully incorporated. More milk will make a softer cake-like biscuit. Drop by spoonfuls onto the prepared baking trays. Press down lightly with a fork. If the fork is sticking, dip it in sugar or water.
Bake for 10 to 15 minutes in the preheated oven, until golden brown. Let stand on the baking tray for a minute before removing to a wire rack to cool completely.
