In Germany, there are two sorts of rolled oats: zarte Haferflocken – finely cut and kernige Haferflocken – which are slightly rougher. If you can get them, use half and half. Otherwise, regular rolled oats. You should not use instant oats or oats that are almost completely ground.
Add or substitute other dried fruit like apricots, figs, cranberries, and so on. You can also leave out completely.
Add or substitute other seeds or nuts. Anything goes.
