Mix pudding powder, 4 tablespoons of milk and 50 g of sugar. Bring the remaining milk to the boil, stir in the pudding powder and bring to the boil again. Cover immediately with cling film and leave to cool, preferably overnight.
For the short pastry, knead flour, hazelnuts, salt, 100 g sugar, fat and egg to a smooth dough. Chill for 30 minutes. Grease a tart mould (26 cm Ø). Roll out the dough to a circle (approx. 30 cm Ø) on a lightly floured work surface.
Lay out the mould with it. Prick the bottom several times with a fork. Bake in the preheated oven (electric: 200 °C/ gas: level 3) for 15-18 minutes. Let cool on a cake rack. Peel and quarter pears, remove core.
Bring wine, lemon juice, 1/4 litre water and vanillin sugar to the boil. Cook the pears for about 10 minutes. Take them out with a skimmer. Leave to cool completely. Beat the pudding with the whisk of the hand mixer until creamy.
Stir in the mascarpone. Spread the cream on the cooled down floor. Arrange the pear halves in a star shape. Chop the chocolate coating and melt in a hot water bath. Thread the tart. Sprinkle with pistachios.
