Mix flour, 1 pinch of salt and milk in a bowl. Stir in eggs, oil and liqueur and let the dough swell for about 30 minutes. Coarsely chop the nuts and roast them lightly in a pan without fat. Take out and let cool down.
Roughly chop the chocolate. Melt butter, chocolate, cream and spread at medium heat while stirring. Let the sauce cool down.
Heat the clarified butter in portions in a pan (approx. 22 cm Ø). Bake 8 pancakes from the dough. Let the pancakes cool down, preferably for about 30 minutes.
Cut the cords in half. Place one scoop of vanilla ice cream in the middle of each crêpe and drizzle with 1 tablespoon of chocolate sauce. Spread 2/3 of the chopped nuts on the crêpes and tie them together with the strings to form packets.
Serve the packet immediately with the remaining nuts and sauce.
