Prepare a double boiler: Fill a small saucepan halfway with water and let it come to a boil. Place a heat-proof bowl on top of the saucepan, making sure the saucepan is not touching the water. Reduce the heat.
Remove the bowl from the double boiler and add the egg yolks and sugar in it. Give it a quick whisk and place the bowl back on the double boiler and whisk continuously with an electric mixer until the mixture becomes pale and creamy. Set the egg mixture aside until it cools down.
4 egg yolks, 80 grams white granulated sugar
Once the egg mixture has cooled down, add the mascarpone and vanilla and whisk again until fully combined.
400 grams mascarpone cheese, 1.5 tsp vanilla
In another bowl, whisk the liquid whipping cream to stiff peaks, then fold it into the mascarpone cream with a silicone spatula in two intervals. make sure you are doing this slowly and gently to retain the airiness of the whipped cream.
320 ml liquid whipping cream
