Method

Pre-heat oven to 160°C fan.

In a bowl cream the sugar with the margarine using a electric hand whisk or food mixer, then add flours & salt, mix together by hand using your fingertips to get a bread crumb constancy.

Grease a non-stick shallow square/oblong baking tin & tip in mixture, spread out evenly then pat down flat or use a mini roller, sprinkle over some extra sugar, then bake for 15 to 20 minutes or until light golden brown around the edges.

Take out of the oven & while still hot & soft scour cut/break lines using a knife a few mm deep into the surface, then allow to go cold, use a pallet knife to lift out pre scoured pieces.
