Roast the almonds without fat in a pan until golden brown. Finely dice the nougat. Whip the cream until stiff and let the cream firmer trickle in. Crumble the Vienna base in a bowl. Add cream, crème fraîche, vanilla sugar, rum and half of the almonds.
Knead everything into a dough. Carefully fold in the nougat. Shape the dough into about 36 balls with your hands. Turn the balls into grated chocolate, cocoa or almonds and refrigerate for about 1 hour. Dust with icing sugar as desired and serve in paper praline cups (3 cm Ø)
