Finely chop the chocolate. Heat the milk in a small pot. Remove from heat and melt the chocolate in it while stirring. Pour chocolate sauce into a sauce boat and put aside.
Roughly chop the nuts. Bring 1 tablespoon of sugar to the boil with 2 tablespoons of water. Add nuts and let them caramelize until golden brown. Spread the nuts on a piece of baking paper and let them cool down.
In the meantime, wash, drain and clean the strawberries. Dice the strawberries. For the cream, cut the vanilla pod in half lengthwise and scrape out the pulp. Whip mascarpone, quark, lemon juice, vanilla pulp and 100 g sugar with the whisk of the hand mixer for about 2 minutes until creamy.
Break nut caramel into pieces. Fill the cream alternately with strawberry cubes in 6 ice cream wafer bags. Sprinkle with caramelised nuts and drizzle with chocolate sauce.
