These are yummy crusty rolls that resemble the delicious rolls my family enjoyed while we were visiting Switzerland. They are easy to make because you measure out all the ingredients for the starter and the final dough at the same time. I find it easiest to weigh out my ingredients on a kitchen scale, directly into my mixing bowl. That is why I have given the ingredients in grams. I have also converted the measurements to cups, however, the recipe works best if measured on a scale.
