Makes 30 big rusks.
650 g of Cake flour
15 ml of cream of tartar
12.5 ml of salt
400 g of sugar
250 g butter/margarine at room temperature,
250 ml buttermilk
10 ml of baking soda
Preheat the oven to 200C. Grease a 45x30x2cm oven tray/ oven pan or spray with a non-sticking agent.
Sift the cake flour, cream of tartar and salt together. Add the sugar and mix. Rub the butter with the fingertips into the flour mixture until it creates fine crumbs.
Mix 25 ml of the buttermilk with the baking soda. Add it to the flour mixture. Beat the rest of the buttermilk and the egg together. Keep 25 ml of the mixture back to brush over the rusks and add the rest to the flour mixture.
Mix well into a dough. Divide the dough into 8 equal pieces. Shape each piece on a floured dough board into a (approx)28 cm sausage and flatten it slightly. Cut each sausage into 4 equal lengths. Place the pieces slightly apart in the pan.
Brush the remaining 25 ml buttermilk and egg mixture onto the rusks.
Bake them for about 30 minutes or until cooked on the middle oven rack.
Let the rusks cool slightly, break them open and dry in a cool oven.
