Mix the two types of flour with the yeast and salt. Add the remaining ingredients and knead into a homogeneous dough. Cover and let rise in a warm place for about 1 hour.
Then knead the dough again. Then form 2 loaves on a floured surface and place in greased bread baking molds. Dust with a little flour and scratch a pattern with a sharp knife. Let the two loaves rise for about 20 - 30 minutes while preheating the oven to 190 ° C top / bottom heat.
