625ml (2.5 cups) cake flour
20ml backing powder
60g of butter or margarine
750ml (more or less) cooking oil
Sift the cake flour, baking powder and salt together into a mixing bowl. Using your fingers mix the butter into the mixture until it starts to look like bread crumbs. Add the egg to the water and beat then add the mixture to the dry ingredients. Mix until it is a soft dough kneading thoroughly. Cover the mixing bowl with plastic cling wrap and let the mixture "rest" for at least an hour.
