Put the gelatin leaf sheets in a bowl with cold water.
Take a springform pan, remove the bottom and place it on a tray.
Dip the Lago Ladyfingers in the blueberry juice and place them inside the pad at the bottom of the tray to make it the base of the cake.
Put together the whipped cream and stir in the yogurt gently, add a pinch of icing sugar.
Place the gelatin leaf sheets in a small pot together with a little water at a medium-low heat on a stove and stir it until it is melted, then add it to the whipping cream and yogurt.
Start spreading the cream over the base of the Ladyfingers and alternate a layer of Ladyfingers dipped in the blueberries juice to a layer of cream up to the top of the pan.
Put the fresh blueberries on the top of the cake and put it in the fridge for at least 5 hours.
When the time is over, take it out of the fridge, remove the springform pan gently and serve it cold.
