For the spiced crispbread, dissolve the yeast in the water. Mix all dry ingredients and knead into a smooth dough with the oil and water-yeast mixture.
Cover and let rise for 15 minutes. Divide the dough in half. Roll out each half very thinly on a sheet of baking paper sprinkled with sesame seeds.
Grind pepper onto the dough with a pepper grinder set not too fine. Roll again well with the rolling pin so that the pepper is pressed into the dough.
Pull with the baking paper on a baking sheet (who has, a perforated) and prick with the fork a few times. Bake in the preheated oven at 180 degrees hot air for about 15 minutes until golden brown.
Immediately pull onto a wire rack to cool. Break into pieces when cold.
