Black Forest Roll Cake

Preparation

1. Prepare the Cherry Filling

1. Combine the cherries and sugar in a small saucepan.As the cherries heat, they will release their juices, creating a fruity base for the filling.
2. In a separate bowl, dissolve the cornstarch in water and add it to the saucepan.Mix thoroughly to avoid lumps; cornstarch helps thicken the mixture evenly.
3. Cook over medium heat until thickened.Stir constantly until the mixture takes on a glossy, jam-like consistency.
4. Add lemon juice, stir, and leave to cool completely.The lemon brightens the cherry flavor and balances the sweetness.
