Prepare everything necessary.
Pour all the flour into a bowl, add 50 g of sugar, baking powder. Cut the cold butter.
200 g flour, 1 tsp baking powder, 150 g sugar, 100 g butter
Crumb the mixture. This can be done with a knife, fork, or quickly rubbed with hands. Beat the egg. Add two-thirds to the dough, leave the rest for glazing.
1 pc egg
Knead the dough. It will be soft, buttery, but should not stick to the hands. In any case, you can add flour during the pie assembly. Wrap the dough in cling film and refrigerate for 30 minutes.
For the filling, pit the cherries, collect the juice separately. If using frozen berries, there is usually a lot of liquid, but if using fresh cherries, you need to take an additional 100 ml of water.
500 g cherry
Put the berries in a saucepan, add the remaining sugar.
150 g sugar
Bring to a boil. Dissolve the cornstarch (1 tbsp) in the cherry juice and pour into the saucepan in a thin stream.
1.5 tbsp cornstarch
Simmer for a couple of minutes until the filling thickens.
Roll out most of the dough into a thin layer, transfer to the form, level the bottom and sides. Here the form is 24 cm in diameter. Sprinkle with cornstarch through a sieve.
1.5 tbsp cornstarch
Distribute the cherry filling.
Roll out the remaining dough, cut into strips and decorate the pie in a lattice pattern. Glaze with the remaining egg.
