Preheat the oven to 180 celsius (355 Fahrenheit) and place all of the ingredients in a food processor and process to combine. The dough probably won't come together completely in your food processor, but will resemble a clumpy sandy mixture. Don't be tempted to add more moisture to bring it together, simply remove the dough from the food processor and place on a piece of baking paper and gently knead until smooth. If the dough is sticky add a little more flour and knead until smooth.
Flatten the dough and place another piece of baking paper on top and roll out the dough using a rolling pin to a thickness of 5mm (⅕ of an inch). Use a cookie 5cm (2 inch) diameter cookie cutter to cut out the cookies and place on a baking tray lined with baking paper. Gently prick all over the crackers with a fork to prevent them puffing up while baking and bake for 12 to 15 minutes, or until golden around the edges. Place on a cooling rack to cool completely before placing in an air tight container, if not serving immediately.
