Dissolve the yeast with the sugar in the lukewarm water.
Knead with the remaining ingredients and let the dough rest for at least 1.5 hours.
Place the dough on a floured work surface and fold it several times. Shape into a loaf of bread and place in a soaked Roman pot. Slightly moisten the surface with water, flour and cut into it with a knife or razor blade.
Place the Römertopf with lid in the cold oven on the lowest level and bake the bread at 240 ° C top / bottom heat for about 50 - 60 minutes. Possibly brown for a few minutes without the lid.
Mashed potatoes mean leftovers from homemade mashed potatoes, from potatoes, milk, butter and salt. No powders or finished products.
