Prepare the Container: Choose a suitable container for your tiramisu, such as a glass dish, ceramic bowl, or mousse mold. Make sure it's clean and dry.
Soak the Ladyfingers: Pour the milk into a shallow dish. Quickly dip the ladyfingers into the milk, ensuring they absorb it but don't soak too long.
Layer the Ladyfingers: Arrange the soaked ladyfingers in an even layer at the bottom of the container.
Add Strawberry Jam: Spread an even layer of the cooled strawberry jam over the ladyfingers.
Add the Tiramisu Filling: Pipe or spoon a layer of the tiramisu filling over the jam, smoothing it evenly with a spatula.
Repeat the Layers: Add another layer of soaked ladyfingers, then top with another layer of tiramisu filling. Smooth the filling evenly.
Refrigerate: Cover the tiramisu and refrigerate for at least 6 hours, or preferably overnight. This allows the flavors to meld and the tiramisu to set properly.
