Melt the fat and let it cool down a little. Put the rusks into a large freezer bag and crumble them finely with the kitchen roll. Knead rusks and melted fat well. Season to taste with sweetener
Grease a springform pan (26 cm Ø), spread the rusk mixture on top and press down firmly with your hands. Put the base in a cool place for about 3 hours
Finely chop the chocolate. Soak the gelatine. Mix quark and 40 g cranberries. Season to taste with sweetener. Stir in chocolate. Squeeze the gelatine, dissolve and stir into the chocolate quark. Whip 200 g cream until stiff. As soon as the chocolate quark begins to gel, fold in the cream. Spread the chocolate quark on the rusk. Put in a cool place for about 3 hours. Wash the pears and steam the halves in a little water for 12-15 minutes. Drain pears well and let them cool down
Remove the cake from the mould. Whip the rest of the cream until stiff, fill into a piping bag with a star-shaped spout and squirt tuffs onto the edge of the cake. Cover with pear halves and decorate the rest with cranberries. Serve decorated with lemon balm as desired
