Cream together 1 cup sugar with butter or margarine and copha. Beat in 2 eggs and add orange zest.
Sift flour and gradually blend into sugar mixture. Dough should hold together and not be crumbly.
Take a walnut sized piece of dough and roll in palms of hand to create a 10 - 15cm rope. Bring ends together to form a circle, and fold ends over each other to make a 'knot.' Brush with a mixture made from beaten egg white and 2 teaspoons sugar; this makes a glossy finish. Add crystallised peel for leaves, and place 1/2 glace cherry at the knot.
Bake at 200C on ungreased baking trays for 10 to 12 minutes. Bake only until biscuits are light brown on bottom - just barely baked.
