From the products that you see in the photo, we will prepare the filling. Pre-steam the raisins with boiling water for 5 minutes, remove the zest from the orange (I like large pieces, but this is a matter of taste), chop the nuts very finely, but not into powder.
In a separate bowl, mix the nuts, sugar, zest, pressed raisins and cinnamon. Mix everything and add milk so that the mixture becomes plastic and it can be spread on a pancake.
Now add the rum. In these pancakes, Karoya Gundel used rum, which gives them a special taste and aroma. But if you cook for children, you can add orange juice or rum flavor instead of rum.
