Plum Cake with Sour Cream

To prepare a delicious plum tart with sour cream, start by preparing the plums. Cut the plums in half, remove the pits, and if the fruits are a bit sour, sprinkle them with cinnamon and optionally with sugar to lightly sweeten them. This step will intensify the flavors and provide a pleasant contrast between the acidity of the plums and the sweetness of the cream.

For the dough, start by cutting the cold butter into small cubes. In a bowl, quickly mix the butter with the flour using your fingers or a mixer with blades to obtain a crumbly mixture. Add one egg and the other ingredients, without over-kneading. It is important that the dough remains soft and does not become elastic. If you notice that the dough does not bind well, add 1-2 tablespoons of cold water, one tablespoon at a time, until you obtain a homogeneous mixture. Once the dough is ready, wrap it in plastic wrap and let it chill in the refrigerator for at least 30 minutes. This step will help the dough become easier to handle.

Before assembling the tart, prepare a springform pan with a diameter of 26-28 cm, lining it with parchment paper. After the dough has chilled, roll it out on a floured surface and use it to line the pan, making sure to cover the sides as well. Then sprinkle the dough with breadcrumbs or crushed cookies to absorb the juice that will be released by the plums during baking.

For the filling, evenly distribute the plum halves over the prepared dough, ensuring they are well-drained so they do not release excess water. In a separate bowl, beat the egg yolks with the sugar until you obtain a light-colored foam. Add the sour cream, cornstarch or pudding powder, and your preferred liqueur, then mix the mixture until homogeneous. In another bowl, beat the egg whites until stiff peaks form, adding a pinch of salt, and carefully fold them into the yolk mixture, being careful not to lose the air in the composition.

Carefully pour the obtained cream over the plums, leveling it with a spatula. Place the tart in the preheated oven at 180 degrees Celsius and bake for about 45 minutes or until the crust is golden brown and the sour cream becomes firm and takes on a golden hue. After removing the tart from the oven, let it cool completely in the pan. Once cooled, cut it into slices and enjoy each piece of this delicacy full of taste and aroma.
