You need a rolling pin, a grater and a little bit of patience for this recipe, as well as all the usual stuff, but the results will take you to biccy heaven.
Ingredients
350g or 12oz Plain flour
25g or 1oz Dark chocolate, melted and cooled slightly
Grated rind of 1 lemon or orange (if using a lemon, use the juice for pancakes)
175g or 6oz butter, softened
300g or 10.5oz caster sugar (that's not confectioner's sugar but sugar which is a bit finer than standard granulated sugar)
1 egg, beaten
Method
Preheated oven, 190°C or 375°F or Gas Mark 5
Grease baking tray.
In a large mixing bowl, cream the butter and sugar until light and fluffy.
Gradually add the beaten egg to the creamed mixture, beating well.
Sieve the flour into the creamed mixture and mix until you get a soft dough.
Transfer half of the dough to another bowl and beat in the cooled melted chocolate.
Stir the grated citrus rind into the other half of the plain dough.
On a lightly-floured surface, roll out the 2 pieces of dough to form rectangles of the same size.
Lay the citrus dough on top of the chocolate dough.
Roll up the dough tightly into a sausage shape. A sheet of baking parchment can help.
Leave the dough to chill in the refrigerator for at least half an hour.
Cut the roll into about 40 slices and place them on the baking trays. (Cook the ends and edges too, don't be fussy, they taste just as good, just watch out for them getting done earlier than the rest.)
Bake in your preheated oven for 10-12 minutes or until lightly golden.
Transfer the pinwheels to a wire rack and scoff before anyone else can get to them.
