Step 1: Make the Cherry Compote

1. In a medium saucepan, combine the cherries, sugar, water, and lemon juice. Bring to a simmer over medium heat, stirring occasionally.
2. Cook for 5–7 minutes, or until the cherries release their juices and begin to soften.
3. Stir in the dissolved cornstarch and cook for an additional 1–2 minutes, or until the mixture thickens slightly.
4. Remove from heat and let the compote cool to room temperature. For faster cooling, transfer the compote to a bowl and refrigerate while you prepare the other components.

Step 2: Prepare the Amaretto Syrup

1. Brew a cup of espresso or strong coffee and allow it to cool completely.
2. Stir in the amaretto liqueur and sugar (if using), adjusting the sweetness to taste. Set the syrup aside.

Step 3: Make the Mascarpone Cream

1. In a large mixing bowl, whip the heavy cream with a hand mixer or stand mixer until soft peaks form. Set aside.
2. In a separate bowl, beat the mascarpone cheese, powdered sugar, vanilla extract, and amaretto liqueur until smooth and creamy.
3. Gently fold the whipped cream into the mascarpone mixture in three additions, being careful not to deflate the cream. The result should be light and fluffy.

Step 4: Assemble the Tiramisu

1. Dip each ladyfinger briefly into the amaretto syrup, ensuring they are moist but not soggy. Arrange the soaked ladyfingers in a single layer at the bottom of a 9×9-inch (or similarly sized) dish.
2. Spread half of the mascarpone cream evenly over the ladyfingers.
3. Spoon half of the cherry compote over the mascarpone layer, spreading it gently to cover.
4. Repeat the layers: another layer of soaked ladyfingers, followed by the remaining mascarpone cream and cherry compote. Smooth the top with a spatula.

Step 5: Chill and Serve

1. Cover the dish with plastic wrap and refrigerate for at least 4–6 hours, or overnight for best results. This allows the flavors to meld and the layers to set.
2. Just before serving, dust the top of the tiramisu generously with cocoa powder. Garnish with slivered almonds or crushed amaretti cookies for added texture, if desired.
3. Slice into squares and serve chilled. Enjoy!
