Soak the cucumbers for one night. Prepare in the soaking water until soft. Remove flower remnants and stems and finely chop the fruit. Mix the nuts with brandy.
Make a dough with flour, a quarter of a liter of cooking broth, sourdough and spices. Knead in cloves and nuts and leave in a warm place (until doubled in volume).
Form loaves with wet hands, put in bread baskets to rise another 1 hour. Turn the loaves out onto a greased baking sheet and moisten them well with water. Put them in the oven heated to 250 °C. After 20 minutes, reduce the temperature to 180 °C and finish baking the loaves (about 1 hour). Brush once with water. The loaves should rest for at least 1 week before serving.
