Chop the raisins and mix with the nuts, sugar, vanilla sugar, egg and rum. Divide the dough into 3 parts and roll out each piece into a rectangle (approx. 30 x 25).
Spread the filling on and roll it up from the longer side.
Put the rolls in a cool place overnight (preferably in the fridge, the snails will stay in good shape while baking and won`t run apart).
Cut the rolls into approx. 1/2 cm thick slices, place them on a baking sheet and brush with the egg milk.
