Mix the dry ingredients together and stir. Wash and coarsely grate the
apple (not the core). Mix all the ingredients together. Preheat the oven
to 200 degrees Celsius with both top and bottom heat, and let the
batter rest while the oven heats up, as this makes it easier to shape.
Wet your hands with cold water and form eight balls that you place on
baking paper. Bake in the oven for about 15 minutes. Freeze what is not
eaten for longer shelf-life of the rolls. :-)
