Prepare the necessary ingredients.
Make the strawberry jam. For this, turn the berries into puree using a blender, then combine with cornstarch and sugar. The mixture needs to be cooked over low heat with constant stirring for 1–2 minutes until the mass begins to thicken.
120 g strawberry, 1 tsp cornstarch, 1-2 tbsp sugar
Pour the ready jam into a bowl, cover with plastic wrap 'in contact' and let it cool completely first at room temperature, then in the refrigerator.
Prepare the cream component of the filling. Using a mixer, combine cream cheese with 40 g of powdered sugar and vanilla. Whip the cold cream 'to soft peaks' with the rest of the sugar, then gently fold it into the cheese mass in several additions using a spatula. Chill the cream in the refrigerator for 30 minutes.
200 g cottage cheese, 130 g cream, 50 g powdered sugar, 1 tsp vanilla extract
Turn the warm sponge onto any flat surface like a large cutting board, previously covering it with a towel. Carefully remove the baking paper, turn the base over again and using the towel, roll it into a roll. In this form, let the pastry cool completely.
Assemble the roll. Unroll the sponge onto a surface lined with plastic wrap, and spread it with strawberry jam.
On top of the strawberry jam, apply a layer of cream, leaving 3–4 cm from the outer edge.
Roll the sponge with the filling into a roll, helping yourself with the plastic wrap. Twist the ends of the wrap tightly, turning the dessert into a candy-like shape. In this form, the roll should stay in the refrigerator for at least 2 hours for the filling to stabilize.
Trim the ends of the ready roll slightly, then decorate with powdered sugar and berries. Enjoy your meal!
