For the dough, knead yeast and 1 tablespoon of sugar until the yeast mixture is liquid. Heat milk lukewarm. Knead flour, 100 g sugar, salt, egg, 50 g butter, yeast and milk with the dough hooks of the hand mixer to a smooth dough.
Cover the dough and leave to rise in a warm place for at least 1 hour.
Wash the currants, drain well and strip the berries from the panicles. Grind the liquorice in the universal grinder. Mix 150 g sugar and liquorice. Knead the dough once more, form it into a ball and roll out approx. 25 x 40 cm on a floured work surface.
Spread evenly with the soft butter. Sprinkle with liquorice-sugar mixture. Spread currants on top.
Roll up the dough from the long side, cut into 12 slices of equal thickness. Spread the slices into the greased and flour-scattered hollows of a muffin tray (12 hollows each). In a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see
manufacturer) bake for about 25 minutes. Let the snails rest in the troughs for about 10 minutes. Remove from the hollows and let them cool down.
