Put the rye together with the caraway seeds through the grain mill (fine). Peel the zucchini, remove any seeds and grate finely so that approx. 150 g remain. Mix the dry and wet ingredients separately and then add them together and mix well (by hand or with the dough hook). Weigh the amount of dough and form 6 rolls of the same weight.
Bake at about 175 degrees for about 30 minutes (I have an old gas stove, I had the setting just below 4)
The zucchini makes the buns quite moist!
1 roll has approx. 23.2 g E - 4.85 KH - 3.18 g F calculated as a layman)
