Put raspberries and water in a medium pot on medium-high heat. Mash the berries with a fork or potato masher. Let it start to bubble, then lower to medium-low and cook for a couple minutes.
02 -
Take the pot off the stove and pour mixture into a mesh strainer placed over a glass measuring cup. Push down on the berries with a spoon or ladle to get all the juice out. Toss the seeds.
03 -
Pour strained juice back into the pot and stir in the lemon juice and sugar. Bring it to a boil, then cook for 4-5 minutes until it thickens up a bit. Let it cool in the fridge until cold.

Using a stand mixer with a whisk attachment, whip up the cream until it holds stiff peaks. Move the whipped cream to its own bowl. Swap out your whisk attachment for the paddle.
05 -
Put mascarpone, sugar, vanilla, and ¾ cup of raspberry syrup in the stand mixer and turn it to high. Once blended, toss in around a cup of whipped cream and mix until smooth. Gently fold the rest of the whipped cream in by hand.

Soak each ladyfinger in raspberry syrup quickly so it doesn’t get mushy. Lay them across the bottom of an 8-inch square pan. Spread half of the mascarpone mixture on top of the ladyfingers. Take a grater or zester and shave half the white chocolate over the top. Repeat with another soaked ladyfinger layer.
07 -
Spoon the rest of the mascarpone mixture on top of the second ladyfinger layer. Put the remaining filling in a piping bag (or a ziplock bag with the tip snipped off) and pipe it in neat rows across the dessert. Sprinkle the remaining white chocolate over the top.

Cover with some plastic wrap and chill for at least 6 hours, better if left overnight.
