Cinnamon Cookies

2 cups self raising (self rising) flour

1/2 tsp (baking) soda

1 tsp ground cinnamon

2/3 cup soft (light) brown sugar

8 tbsp butter

1 tsp lemon juice

1 tsp orange juice

1 egg, separated

2 tbsp caster (granulated) sugar

Sift the flour, soda and 1/2 teaspoon of the cinnamon into a bowl. Rub in the butter, then stir in the brown sugar. Add the juices, egg yolk and enough of the egg white to make a dough. Roll out the dough thinly and cut into 2" rounds. Place on greased baking sheets. Brush with the rest of the egg white, lightly beaten. Mix the white sugar with the remaining cinnamon and sprinkle on top. Bake in a preheated moderately hot oven (375 degrees) for 15 to 20 mins. Makes about 50.
