Drain the sour cherries over a sieve, collect the juice and fill up to 500 ml with the red juice.
Bring the juice with vanilla sugar and sugar to the boil (hold back some juice to mix the starch), then bind with the mixed starch. Add cherries and raspberries, stir carefully and let cool down a little.
Place the filling on the dough base and bake at 200 ° C for about 20 minutes on the middle rack.
