1: 225 g flour, 75 g icing sugar, vanilla sugar, half lemon zest, 1 pinch of salt, 150 g butter in small pieces and 2 tablespoons cold water, first with a hand mixer, then briefly knead with your hands until smooth.
Cover and chill for about 30 minutes.
2 Springform pan (26 cm Ø and at least 7.5 cm high or 28 cm Ø) lightly greased. Roll out just under 2/3 of the dough (approx. 300 g) onto a little flour and place on the bottom of the mould.
Cover the edge of the springform pan. Form the rest of the dough into 2 rolls (each approx. 34 cm or 42 cm long). Place the dough rolls on the inside of the tin and press them up about 3 cm. Prick the dough base several times with a fork.
Pre-bake in the preheated oven (electric oven: 200°C/circulating air: 175°C/gas: level 3) on the lowest rail (gas: see oven manufacturer) for approx. 20 minutes.
Mix 250 g butter, sugar, 1 pinch of salt and the rest of the lemon zest with the hand mixer for 2 to 3 minutes at most. Mix eggs and pudding powder with the hand mixer only briefly until the pudding powder is dissolved (otherwise the cake will rise too much!).
Stir in the quark. Add the quark mixture to the butter in 2 portions and mix everything smooth.
Remove the mould from the oven. Turn down the oven (electric cooker: 175°C/circulating air: 150°C/gas: level 2) Spread the short pastry base with jam. Spread curd cream on top (the smaller mould is almost full to the brim) and sprinkle with almonds.
Continue baking on the lowest rack for approx. 1 1/4 hours. After approx. 30 and 50 minutes baking time, remove the cake from the edge with a knife. Leave the finished cake to rest for 5-10 minutes in a switched-off oven.
Cool down in the mould for about 4 hours. Dust with icing sugar.
