Knead 300 g flour, 200 g butter in pieces, 100 g sugar, 1 pinch of salt, 1 egg and ice-cold water until smooth. Wrap short pastry in foil and put it in a cool place for about 30 minutes.
Drain the cherries and let them drain well. Preheat the oven (electric cooker: 180 °C/circulating air: 160 °C/gas: see manufacturer). Grease a springform pan (approx. 28 cm Ø). Approx. 2⁄3 Roll out short pastry round in the size of the springform pan and press it onto the bottom of the springform pan.
Roll out the rest of the dough to a strip about 3 cm wide and press it evenly into the tin as a rim.
Spread the cherries on the floor. Mix sour cream, cream, 4 eggs, 100 g sugar and starch. Spread on the cherries. Bake in a hot oven for about 1 hour until golden brown. Take out of the oven and let cool a little on a cake rack.
Remove from the mould and allow to cool completely.
