Lemon Pie

Combine the sour cream with the baking soda. Add the melted butter to the sour cream and stir until smooth. Gradually incorporate the flour in small portions. Add 1.5 cups and check the consistency: if the dough still sticks to your hands, mix in the remaining half cup.

Knead the dough and divide it into 2 equal parts. Cut the oranges/lemons into small wedges (with the peel on), blend them until smooth, and mix with 1 cup of sugar.

Preheat the oven to 180°C. Press half of the dough into the base of a greased baking pan, spreading it evenly across the bottom and up the sides to form edges. Spread the filling evenly over the crust. Cover the filling with the remaining dough. Brush the top of the pie with beaten egg yolk. Poke the surface of the pie a few times with a fork.
