Begin by collecting together all of your ingredients. If you're making your own syrup and curd, you'll need to have these both ready and cooled.
In a large mixing bowl, beat together the heavy cream and vanilla just until stiff peaks are formed. Avoid overbeating here or your cream will become denser than you're ideally looking for.
¾ cup heavy cream, 1 teaspoon vanilla extract
In a separate bowl, whisk together the mascarpone, half of the blackberry curd and salt. Again, avoid overbeating as mascarpone has a tendency to become a bit grainy when overworked.
8 oz mascarpone cheese, 1 pinch salt, 1 cup blackberry curd
Add your whipped cream to the mascarpone mixture and fold together to incorporate. Set this aside while you begin assembly with the ladyfingers.
Begin dipping the ladyfingers into your syrup (mixed with liqueur if using). Dip each ladyfinger into the liquid and flip it over to ensure it gets a good soaking, without becoming mushy. Then, place the ladyfingers in your serving dish.
½ cup blackberry syrup, 1 tablespoon Chambord, ladyfingers
Once you have formed a layer of soaked ladyfingers in your tray, spoon about half of your cream mixture on top. Spread this out into a smooth layer.
Repeat the process of dipping ladyfingers and arranging these in your dish, on top of the cream. This will form a second soaked ladyfinger layer.
Top off the ladyfinger layer with your remaining cream, spreading as smooth as possible.
Cover with plastic wrap - gently pressing this directly onto the cream. This will avoid the cream developing a skin in the refrigerator. Place the tiramisu in the fridge to chill for at least 4 hours (or overnight).
Before serving, top with the remaining curd and garnish with some berries!
