Boil the syrup from sugar and water to 118 degrees (I described the process above).
In parallel, whisk the yolks white. Enter the syrup in a thin stream, continuing to beat with a mixer at high speed and pulling the bottom of the bowl so that the syrup does not settle to the bottom and does not freeze. We need a smooth creamy texture.
In the microwave, we dissolve the gelatin and add it to the yolk base for our cream.
When the mass cools down to 40 degrees – add cold butter, cut into small cubes. Whisk until smooth. We also send our mascarpone there. If grains have formed in the cream, it does not matter! Put the bowl on a steam bath and, with constant stirring, whisk until smooth. Cool.
