Have an eight or nine-inch baking dish ready.
Pour the cool syrup into a wide bowl, and dip the bottom of the ladyfingers.
Arrange the soaked ladyfingers in a single layer over your serving dish.
Spread half of the filling over the cookies and use a rubber spatula to spread it evenly.
Drizzle half of the lemon curd over the surface of the cream, then use a toothpick to create swirls.
Repeat with the remaining ladyfingers, cream, and lemon curd, and place in the refrigerator to set for at least four hours.
When ready to serve, whip the heavy cream with the sugar and vanilla and use a piping bag to pipe the cream over the Tiramisu.
