In a bowl, combine the sugar, flour, cinnamon and orange rind.

Spread the mixture in a 2 L glass cake pan and cook in the oven at 200°C (400°F) for 10 minutes.
In a large bowl, combine the flour, sugar, baking powder, baking soda and salt.
Add the margarine and, using two knives or with your fingers, work the mixture until it has the consistency of peas.
