Preheat the oven to 180 C and line a few trays with baking paper.
Put all the ingredients into a food processor or electric mixer fitted with paddle attachment.
Pulse or mix on low until the ingredients come together and form a dough.
Roll the dough out on a lightly floured surface until it is ¼cm thick.
Cut out crackers of whatever shape and size you like. I made little circles about 1 inch in diameter. Prick the center of your shape with a skewer to prevent them from puffing up in the oven.
Gather any excess dough together, roll it out and repeat the process until you have used up all your dough.
Bake until they turn golden around the edges. Baking time will depend on the size of your crackers, but mine took 12 minutes.
Allow to cool and serve with beer (optional but highly recommended!). Makes about 100 crackers.
