Stir the sugar and yeast into the lukewarm milk and leave for about 5 minutes.
Knead the flour, salt and butter in a mixing bowl. Add the yeast-milk and knead for approx. 15 minutes to form a smooth dough.
Cover the dough and leave to rise in a warm place for approx. 90 minutes.
Filling
Mix the tahini with the sugar and cinnamon.
Roast the hazelnuts properly in a pan and then chop them.
Chop the chocolate.
Prepare tahini chocolate buns (there is an easy and a more elaborate method).
Turn the dough out of the bowl onto a floured work surface.
Roll out the dough into a rectangle with a rolling pin. (Approx. 85cm long)
Spread the tahini-sugar mixture over the rectangle.
Spread the chopped chocolate and hazelnuts on top.
Knots (somewhat more elaborate method)
Fold in one side of the rectangle to the middle. So one half is still free.
Pull the other side of the rectangle completely over the other. So now it is an elongated rectangle with 3 layers. Gently roll this smooth and slightly thinner with the rolling pin.
Using a sharp knife or pizza cutter, cut the short length of the rectangle high into approx. 12 equal strips.
Cut each of these strips in the middle about 4/5. You now have a pair of trousers. Cross the trouser legs as many times as you can and then join the two ends together. You now have the dough pieces.
Snails (simple method)
Roll up the rectangle and cut into approx. 12 equally sized snails.
Baking
Let the dough pieces/snails rest on a baking tray lined with baking paper with a good distance between them (Dough Distancing!) for another approx. 30 minutes.
In the meantime, preheat the oven to 220 °C.
Bake the pastries for approx. 8 minutes in the preheated oven.
Topping
Melt the chocolate over a water bath.
Pour the chocolate, hazelnuts and tahini over the snails.
