Exquisite Pavlova Cake

Preparation:

1. Without turning off the mixer, first beat the egg whites with a pinch of sugar, then gradually add 150 g of sugar and continue beating until thick, stiff peaks form.
2. Fold the starch into the meringue with a spatula until it is fully dissolved.
3. On a baking sheet lined with parchment paper, use a dessert plate to trace two circles. Spread the meringue mixture evenly within each circle, making the edges slightly higher than the center. Place in a preheated oven and bake for 2 hours at 90°C.
4. To make the cream, whip the powdered sugar and heavy cream together until thick. Spread the cream over one of the cooled meringue layers. Arrange the berries on top of the cream and gently place the second meringue layer on top.
4. In a separate deep bowl, thoroughly mix the sugar with the cocoa. Gradually, thin the mixture by stirring in the water first, and then the butter, until it is completely dissolved.
5. Pour the prepared chocolate over the top cake layer, starting from the center so that it drips down the sides of the cake.
6. Then, decorate the cake with raspberries, whole strawberries, as well as quartered strawberries and blueberries. The berries should be slightly pressed into the chocolate. Finally, dust the berry topping with powdered sugar using a sieve.
