Put all dry ingredients in a bowl and stir well so that the heavily swelling psyllium husks are not in one place in the bowl.
Gradually add the water and stir the dough-like mixture. The dough should soak for 15 minutes if necessary, you can then add more water. However, the consistency should not be liquid, but rollable with a rolling pin.
Preheat the oven to 150 degrees, the baking time is approx. 60 minutes, if the dough is a little thicker, a few minutes more.
Place the dough on a baking sheet lined with parchment paper. Put a baking paper on top and roll out the dough with a rolling pin. Before the tray goes into the oven, cut “predetermined breaking points” into the dough with the back of a knife. The amount is enough for 1 tray.
The storage of dry baked goods is similar to other crispy baked goods with very little residual moisture, but the bread does not get very old here.
