How to make apple pie with strawberries step by step

Step 1 - Preparations

• Line the cake tin with baking paper (to make the paper stick well, I grease the tin in a few places - on the bottom and on each side - with a little butter, to which the paper adheres).
  
• Wash the strawberries, remove the stems, and cut them into smaller pieces - halves or quarters - depending on the size of the fruit.
  approx. 1 kg strawberries

Step 2 - Preparing the pie crust

• Transfer the flour, baking powder, butter cut into smaller pieces, and sugar to a bowl.
  300 g all-purpose flour, 0.5 teaspoon baking powder, 150 g butter, 2 tablespoons powdered sugar
  
• Carefully crack the eggs, separate the yolks from the whites - add the yolks to the shortcrust pastry ingredients, and transfer the whites to another bowl.
  4 egg yolks
  
• Knead the dough - it may still be slightly crumbly.
  
• Pour the dough into the form and carefully line the entire bottom with it.
  
• Place the form with the dough in the refrigerator and preheat the oven to 180℃ (top/bottom heating mode).
• Once the oven is preheated, place the form with the chilled dough inside and pre-bake it for 20 minutes.

Step 3 - preparing the strawberries

• While the dough is baking, prepare the strawberry filling.
• Add sugar and potato starch to the cut fruit - mix thoroughly.
  100 g sugar, 65 g potato starch
  

Step 4 - preparing the meringue for the apple pie

• Start lightly mixing the reserved egg whites.
  4 egg whites
  
• Start slowly adding sugar in portions and mix together at high speed with a mixer.
  150 g sugar
  
• Once you've added all the sugar and the egg whites are very thick and white, check if the meringue is well-made - take a small amount of meringue on your finger and rub it between your fingers - if you don't feel sugar crystals, then the meringue is well-mixed.
  
• Add potato flour and lemon juice to the egg whites and mix briefly.
  1 teaspoon potato starch, 1 teaspoon lemon juice
  

Step 5 - preparing the dough

• Remove the form with the pre-baked crust from the oven and lower its temperature to 140 ℃.
• Spread the strawberries on the base - if they have released juice, do not add it!
  
• Spread the meringue over the strawberries and smooth it out.
  
• Place the form in the oven and bake the cake for about 40 minutes.
• After baking, cool the cake thoroughly and serve when it is cold.
