Very tender lemon pie

Ingredients:

Sour cream — 250 g
Butter — 110 g
Baking soda — 1/2 tsp.
Flour — 2 cups
Lemon/orange — 1.5 pcs.
Sugar — 1 cup
Egg yolk — 1 pc.
Powdered sugar

Preparation:

1. Mix sour cream with baking soda.
2. Add melted butter to the sour cream, stir until the mixture is homogeneous.
3. Gradually start adding flour in small portions. After adding 1.5 cups, check: if the dough sticks to your hands, add the remaining half cup. Otherwise, it's not necessary. Knead the dough and divide it into 2 equal parts.
4. Cut the oranges/lemons into small wedges (with peel) and blend in a blender.
5. Mix the blended lemon with 1 cup of sugar.
6. Preheat the oven to 180 °C. Place half of the dough as the base. Spread the dough over the entire surface of the pan, making slight edges.
7. Spread the filling and evenly distribute it over the entire base.
8. Crumble the second part of the dough with your hands and cover the filling with it.
9. For a golden crust, brush the pie with beaten egg yolk.
10. Prick the pie with a fork. Bake for about 30 minutes. Then cool and remove the pie from the pan and sprinkle with powdered sugar.
