Mix all the ingredients together in a bowl. The dough should be quite sticky. Place half of the dough on a piece of baking paper. Put another piece of baking paper over the dough and roll it out thinly between the two pieces of paper so the dough covers the entire surface. Repeat the process with the other half of the dough. Place the rolled-out dough pieces on separate baking trays. Remove the baking paper from the top of the dough on both trays. Bake the crispbread in the oven at 195 degrees Celsius (383 degrees Fahrenheit) convection for about 10-15 minutes.
