Mix all ingredients together into a firm dough.
Divide the dough into two equal parts and roll each part out as thinly as possible. Cut out your crackers in the desired shape and place them on a baking sheet.
Bake for about 15 minutes in an oven preheated to 230 degrees Celsius (446 degrees Fahrenheit).
Let the crackers cool for several hours so they have time to set and firm up.
