To a heat proof mixing bowl, add granulated sugar, egg yolks and vanilla paste. With a hand whisk, whisk it until lighter and fluffy, about 1-2 minutes.
225 g granulated sugar, 6 egg yolks, 1 teaspoon vanilla paste or extract
Place the bowl over a pot of simmering water, to make a double boiler. Continue whisking constantly for 5 minutes so it thickens and becomes lighter and even fluffier and most of the sugar has mostly dissolved.
Take it off the heat and dry the bowl. Add the mascarpone and continuing with the hand whisk, whisk it together until just combined and no lumps appear.
450 g mascarpone cheese
In a separate bowl, whip the heavy cream until stiff peaks. Add the whipped cream to the mascarpone filling and gently fold it together using the hand whisk. Using a rubber spatula, scrape down the sides of the bowl, and give the filling a gentle fold to make sure all of the ingredients have combined.
300 ml 280 g heavy cream
Use a serving dish thats 27x20 cm (8x10.5 inch) or 23x23 cm (9x9 inch) or anything similar in that size.
Dip the lady fingers into the rhubarb syrup twice on each side.
30 ladyfingers
Lay the lady fingers in a layer in the serving dish. Add half of the mascarpone cream and even it out into an even layer. Then gently dollop half of the rhubarb compote over the mascarpone cream, a gently event it out. Repeat the process, except the last half of the rhubarb compote.
Add plastic wrap over the mascarpone cream and let it set in the fridge for a minimum of 4 hours or preferably overnight.
Once ready to serve, add the remaining rhubarb compote on top of the tiramisu and it’s ready to be enjoyed.
