Add flour, yeast, German bread spice (optional) and sugar to a bowl and blend briefly.

Add warm water and knead for about 10 min.

Cover with a clean kitchen towel and allow to rise for about 20 min.

In the meantime, cook the potatoes.

Rice the potatoes and add them with salt and the eggs to the dough.

Knead the dough for about 10 min.

Depending on the potatoes add gradually up to 4 more cups flour. The dough should still be soft.

Cover and let rise for about 1 hour.

In the meantime, preheat the oven to 400 F and place a large heatproof bowl or pan with water in the oven.

Add the dough to a floured working area.

The dough will be pretty sticky. Flour well and tuck ends of the dough under to round it.

Sprinkle the bread lightly and slash with a sharp knife.

Bake at 400 F in a preheated oven for 40 to 60 min.
